2 Basic information Dry Disconnect Couplings are safety components. They facilitate fast coupling and decoupling of filled hose and pipe lines under pressure without significant leaks or loss of the handled fluid. They are used everywhere where people and/or the environment need to be protected from hazardous leaks of media (caustic, toxic, explosive, etc.), or vice-versa when sensitive media (e.g. foodstuffs as well as pharmaceutical and fine chemical products) need to be kept safe from environmental contamination. Depending on the field of application, different technical designs are needed, all of which however work on the following basic principle: Both coupling halves in the separated (decoupled) state are blocked by a sealing mechanism so that no media can escape. When coupling, both halves are initially connected with each other tightly sealed before the sealing mechanism can be opened and a flow channel inside the coupling is enabled. Vice-versa, before separation, both coupling halves are first closed again so that the flow channel is blocked. For this purpose, dry disconnect couplings are equipped with the following basic functions: 1. Safe connection of the coupling halves. Female and male couplings are impermeably connected to one another. 2. Sealing mechanism for both coupling halves to prevent the media from leaking. 3. Safety in design. The mandatory operating sequence of points 1 and 2 prevents undesirable product leakages. 4. Integrated swivel joint in order to prevent hose torsion. 5. Depending on the application, there are different coupling types, which differ primarily in terms of their valve form, e.g. disc valve, sleeve valve and ball valve. Your benefits at a glance Quick coupling without significant media loss Matching coupling technologies for various requirements Protects humans and the environment from leaking hazardous substances Customer-specific special solutions from DN 25 to DN 150 Only a specialist is qualified to clearly specify the choice of a suitable dry disconnect coupling. Each application always requires individual requests and advice. That is why we have restricted this catalogue to the technologies typically used in the broad market. A distinction is made here between the valve-controlled sealing systems and the "Full Flow" constructions. 2

6 TX series The completely NEW generation that is also STANAG-compatible Functional principle This coupling series meets the up-to-date requirements - but is designed around a basic bayonet principle according to STANAG 3756 that is tried and tested for decades, i.e.: The TX dry disconnect couplings consist of two coupling halves (male and female couplings), each of which is equipped with a disc cut-off valve. Coupling is performed by pushing the male half axially into the female half. A rotary motion creates an impermeable connection between the two coupling halves. Further rotation by approximately 100 opens the valves by transmitting a sliding action into the centre of the male coupling, which opens a ring-shaped flow channel. During the uncoupling operation, the rotatory movement is performed in the opposite direction: The flow channel in both coupling halves is impermeably sealed before the coupling halves can be separated.

12 TR series The coupling for chemicals and very special applications Functional principle To couple, the female coupling is placed on the male coupling and then turned clockwise. While doing so, the male section is pulled into the female section through its helical grooves on its exterior. After a 10 rotation, both halves are permanently connected. After that, the valve positions shift offset to the valve seats, so that the valve pair is positioned after a turn of a total of 120 into the expanded line cross section of the male coupling, releasing a ring-shaped flow channel. During decoupling, the process runs in the reverse sequence. The special characteristics Virtually residue-free coupling Excellent coupling ergonomics Sensor applications for connection monitoring available Multiple mechanical coding variants to avoid connection mix-ups: Using key/lock logic Using spool sizes/control cam depths TR series coupled and decoupled 12

15 TR series application examples The TR in use in an explosion protection zone at a chemical plant. Undesirable and hazardous media leakage is thus avoided. Further information is also available on our website In use as a secure quick coupling in a multi-purpose facility at a chemical plant. For process optimisation, flange systems were replaced by the TR series. The colour coding as well as the mechanical coding used on one variant (green) avoid connection mix-ups and therefore the unintentional mixing of amines and nonamines. In use in a distributor station for a filling line at a chemical plant. Six hose lines each fitted with a hose unit can be connected quickly and without media leakages to a selection of 10 pipe lines, each of which is equipped with a tank unit. In use for loading rail tank wagons with ethanol at a chemical plant. Simple, quick and leak-free coupling and decoupling of the discharge line is guaranteed. For added safety, the TR dry disconnect coupling in this application is supplemented by an RS breakaway coupling from the ABVL series. 15

16 TD series The special solution for steam applications Functional principle TD dry disconnect couplings consist of two coupling halves (male and female couplings), each fitted with a cut-off valve. Coupling is performed by means of a rotary movement that pulls the male coupling into the female coupling by means of the helical grooves. After 10, the hose unit and the tank unit are connected. At up to 120, the valve position shifts relative to the valve seat the full, unobstructed flow of the medium is guaranteed. When the coupling is opened (unscrewing the cam disc mechanism), the shut-off valves in the coupling halves close before the halves themselves are separated, which prevents the uncontrolled escape of hot steam.

20 TK series Full flow coupling with ball valve Functional principle of basic model The TK series dry disconnect couplings consist of two identical (TKU, unisex) or two virtually identical (TKV & TKM, male and female) coupling halves, which in the decoupled state are each closed by a cut-off valve based on the ball valve principle. The connection between the two coupling halves is realised by cleats. The connection is secured by turning the two coupling halves 90 relative to each other. After coupling, the two ball valves are opened by a lever on each side and the full flow cross-section is released. An integrated interlock function prevents accidental decoupling while the flow cross-section is open inadvertent opening of the flow cross-section while in the decoupled state and the resultant undesirable media loss Premium model The TKM/TKV premium model basically works according to the same principle, and consists of two non-identical coupling halves. The coupling offers all the advantages of the standard chemical variant (TKU). It is also optimized for use with viscous and quick-hardening media. Flow cross-section optimised in terms of dead spots Suitable for quick-hardening, crystallising and lowviscosity media Media with very high resistance requirements Coupling consists of a female and male parts (with regard to the separation point) TK series coupled and decoupled 20

23 TK series application examples In use for instantaneous connection of a gas displacement line for loading tanker trucks in a chemical plant for the production of colour pigments Further information is also available on our website In the unloading station (delivery) of a filling plant operated by logistics provider for hazardous chemical substances. The dry disconnect coupling function reduces the respective set-up times, guarantees rapid coupling and decoupling, and eliminates the need for various time-consuming additional measures to protect humans and the environment. Furthermore, the full flow rates provided ensure that short loading times are maintained. In use for disposing of combustible sludge on a feeder ship. Compared to the previously used flange solutions, the effort involved in connecting the disposal line is significantly reduced while the level of cleanness is drastically increased. 23

24 TC series The cryogenic couplings for cryogenic applications down to -196 C Functional principle To couple, the female section is placed on the male section and then turned clockwise. While doing so, the male section is pulled into the female section through its helical grooves on its exterior. After a 10 rotation, both halves are permanently connected. After that, the valve positions shift offset to the valve seats, so that the valve pair is positioned after a turn of a total of 120 into the expanded line cross section of the male section, releasing a ring-shaped flow channel. During decoupling, the process runs in the reverse sequence. The special characteristics The highest flow rates Highest flow rates of all competitor products Leakage rates No media leakage during operation and coupling procedure Adherence to required leakage in line with applicable regulations RS operates suitable test facilities to guarantee these low leakage rates Optimisation for low temperatures prevents failure Coupling connection sealed from the environment Coupling can be operated at any time Coupling and decoupling under operating conditions (-196 C) with no media leakage No moisture ingress and no resulting icing of the coupling connection Anti-icing protection does not impair coupling Ergonomic design Handling the coupling does not require high forces Rapid coupling and decoupling of filled and pressurised hoses and pipe lines is possible Design stops coupling from cooling too quickly Simple handling Coupling and decoupling by simply turning the hand wheel 120 turn to the right = coupled and open 120 turn to the left = decoupled and closed No training required for personnel Suitable for additional technical gases The TC can also be used for argon, liquid nitrogen and even liquid oxygen 100% grease-free 24

It indicates that the construction of the component has been checked and approved for use in the respective provinces. The organisation responsible for issuing the CRN is called the TSSA. The approvals mentioned above have been applied for and the approval statuses are progressing at different rates.

27 TC series technical data In use at a container for mobile supply of container ships using LNG as a fuel. The TCV male couplings are attached to the container. The female couplings are connected on the ship. Further information is also available on our website In use for refuelling tanker trucks with LNG. Compared to the refuelling fittings previously used, the handling procedure is drastically simplified. In addition, the design prevents the ingress of moisture and the resulting icing and freezing of the coupling halves. 27

29 Threads and flanges 1 Threaded connections Threaded connections are generally classified according to male and female thread. A further distinction is then made according to thread types, which perform very different sealing functions quite apart from the thread structure. Some threads transfer the force in order to create a flat or conical seal (not in the thread). The other type of seal is created in the thread itself. Overview of threads commonly used in valve technology Description Standard Application areas General International G-thread BSP DIN EN ISO 228 R-thread BSPT DIN 2999/EN NPS NPS ANSI/ASME B NPT NPT ANSI/ASME B /3 General industry Milk pipe round thread Round thread DIN Foodstuffs, Pharmaceutical ACME ACME ASME B1.5 Gas Metric ISO-thread Metric thread DIN 13 Hydraulics 51/2" rail tank wagon thread DIN 11 Loading rail tank wagons Overview of identifying features Description Male thread Female thread G-thread cylindrical cylindrical with seal R-thread conical cylindrical without seal NPS cylindrical cylindrical with seal NPT conical conical Milk pipe round thread cylindrical with seal cylindrical ACME cylindrical with seal cylindrical with sealing face Metric ISO-thread cylindrical with cone cylindrical with conical face 51/2" rail tank wagon thread cylindrical cylindrical with seal Overview of types of seal Description Seal type Sealing point Compatibility Notes G-thread flat Thread seal R-thread if AG flat sealing R-thread conical Thread + sealing band G-thread if AG flat sealing NPS flat Thread seal NPT NPT Thread Thread + sealing band NPS if AG flat sealing Milk pipe round thread flat Thread seal ACME flat Thread seal Metric ISO-thread conical Cone/metallic 24 or 60 degree cone 51/2" rail tank wagon thread flat Thread seal 29

30 Threads and flanges For safety fittings with a threaded connection generally only use BSP and NPT threads: BSP NPT 2 Flanged connections D K B3 L C1 Flange outer diameter Hole circle diameter Central hole diameter Hole diameter Flange thickness Flange connections are divided into lapped flanges and fixed flanges. The lapped flange can be turned on the hose or on the plant and can be aligned with its counterpiece. As the name implies, fixed flanges are fixed to the plant or to the hose and cannot be turned. For this reason, a hose fitted with flanged connections at both ends will have a lapped flange on at least one end. This prevents hose torsion, which occurs if both ends are fitted with fixed flanges. Flanged connections are generally standardized in the same way as threads. These standards are broken down further into pressure stages. Depending on the pressure stage, the flanges differ, for example, in terms of outer diameter, hole circle, number of holes, flange width etc. Lapped and fixed flanges of the same standards and pressure stages are compatible with one another. ANSI (ASA) flanges are not compatible with DIN or EN flanges. Flanged connections are attached at the front with the aid of a suitable flange seal, screwed on with nuts and bolts and thus sealed. Safety couplings with flanged connections are always delivered with fixed flanges. 30

Depending on the fitting, these materials are selected based on standards and/ or applications. Factors such as strength, chemical and thermal resistance as well as manufacturing processes play a major role in the choice of material. The following main groups products are used in the most diverse variants and qualities in valve technology: Overview of the most widely used materials in valve technology Materials by manufacturing process Material groups Machined (turned/milled) Cast Forged Injected Steel , , , Stainless steel 2A grade , , Stainless steel 4A grade , , , Hastelloy , , , Brass CW614N, CW617N CW614N, CW617N CW614N, CW617N Aluminium EN AW-6060 EN AC EN AW-6082 Plastics Polypropylene, PEEK, PTFE, POM Polyamide For safety coupling stainless steel, aluminium or (rarely) brass are usually used. 31

32 Threads and flanges 3.2 Materials for seals The large number of thread and coupling seals require varied variety of materials for seals. Elastomeric seals are common for this purpose. Overview and characteristics of the most widely used sealants in fitting technology Material Chemical properties Physical properties FKM/FPM (Viton) NBR (Perbunan) Polyurethane (Vulkulan) PTFE (Teflon) CSM (Hypalon) FFKM (Kalrez) Novapress Multi EPDM Good general chemical resistance good ozone & weathering resistance Good resistance to petroleum & fuel limited ozone & weathering resistance Good resistance to petroleum & fuel poor chemical resistance Universal chemical resistance good ozone & weathering resistance Good acid & lye resistance good resistance to petroleum & fuel excellent chemical resistance Good steam & hot-water resistance good resistance to petroleum & fuel Good steam & hot-water resistance poor resistance to petroleum & fuel good ozone & weathering resistance High temperature resistance at water & water vapour max. 60 C operating temperature C Good mechanical properties (abrasion resistance) good low-temperature behaviour temperature range C Good mechanical strength (wear & tear resistance, elasticity) operating temperature C Good anti-friction properties high temperature resistance operating range C Good mechanical strength (wear & tear resistance, elasticity) operating temperature C High temperature resistance operating range C High pressure resistance operating range C Good mechanical strength (wear & tear resistance) operating temperature C Depending on the particular application, a suitable sealant must also be used in addition to the suitable valve material. Please contact the manufacturer of the safety fittings for assistance in choosing an appropriate seal. 3.3 Surface finishing/ surface protection Corrosive media call for special fittings which provide suitable surface protection. For protection against aggressive media such as acids and lyes, highly chemical-resistant fluoroplastic coatings are used. These include PTFE, FEP, E-CTFE, ETFE, or PFA. This coating is applied to areas that come into contact with the media. Unfortunately, not all parts of a coupling assembly can be coated.in this case highly chemical-resistant materials like nickel-based alloys (e.g. Hastelloy or Inconel) are used. 32
