38 COPPER WINDING TEMPERTURE CLSSIFICTION Insulation systems are arranged in order of their insulation level and classified by a letter symbol or by a numerical value. The numerical value relates to the temperature classification of the insulation system. The temperature classification indicates the maximum (hotspot) temperature at which the insulation system can be operated for normal expected service life. In general, all materials used in a given insulation system should be rated for temperatures equal to, or exceeding, the temperature classification of the system.

39 METLS g (silver) Silver is a soft, malleable metal with a characteristic sheen. It has the highest thermal and electrical conductivity of all metals. lcon provide shading coil material for stainless steel valves in silver. I (aluminium) Derived from the Latin LUMEN for LUM (Potassium aluminium sulphate). lightweight material that offers high strength and rigidity along with good corrosion resistance and heat dissipation. lcon provide die-cast bodies, solenoid enclosures and shading coils made from aluminium. Cu (copper) Copper is an important engineering material since it is widely used in its pure state and also in alloys with other metals. In its pure state it is the most important material in the electrical industry. It has high electrical conductivity and corrosion resistance and is easy to fabricate. It has reasonable tensile strength, controllable annealing properties and general soldering and joining characteristics. lcon provide as standard shading rings produced from Copper. CU Sn (bronze) Bronze alloys consist of copper and tin primarily and these can be known as "tin bronzes". Since phosphorus is usually added to these alloys as a deoxidising agent during casting, the tin bronzes are commercially known as "phosphor bronzes". These alloys possess desirable properties such as high strength, wear resistance, and good sea water resistance. lcon provide bodies from bronze. Fe CrNi 300 Series (8-8) ustenitic 303 is essentially low-carbon steel to which chromium has been added. It is the addition of chromium, in amounts of 8%, that adds strength and gives stainless steel its unique 'stainless', corrosion-resisting properties. The corrosion resistance, as well as other useful properties of the steel, is enhanced by the addition of other elements such as 8% nickel. lcon provide flange tubes, bodies & springs in 300 series stainless steel is essentially low-carbon steel to which chromium has been added.

40 MODES OF OPERTION / N/C Normally Closed Solenoid Operated Direct cting Solenoid Pilot Operated way, normally closed, energise to open, on/off operation (de-energise to close), with one inlet and one outlet connection. There are types of valve operation Direct cting and Pilot Operated. a) Direct cting The coil supplies all the power to open the valve and the valve will operate from zero pressure. b) Pilot Operated this can either be diaphragm or piston operated. These valves have a pilot hole which is opened/closed by the coil acting upon a plunger and diaphragm or piston used to control the main Orifice (mm). The operation relies on the media pressure difference between the inlet and outlet and a minimum operating pressure is required to operate these valves unless stated as zero. / N/O Normally Open Solenoid Direct cting Solenoid Pilot Operated way, normally open, energise to close, de-energise to open, with one inlet and one outlet connection. Can be either direct acting or pilot operated. 3/ N/C Normally Closed Valve open when energised, closed when de-energised. This valve operates on the same principle as the / N/C version except the valve has 3 connections, orices, one permanently open, one permanently closed. The use of these are for operation of actuators for large valves where single cylinder spring return system is employed. 3/ N/O Normally Open Valve open when de-energised, closed when energised. 3/ UNI Universal Valve may be used as normally closed, normally open or diversion/selector valve. / These valves are available in forms; a) Single Solenoid position, spool and sleeve type, which is based on an air pilot return mechanism. When de-energised, the valve allows one inlet and one outlet to be connected, exhausting the other inlet/outlet connection through an exhaust port. On energisation, the action reverses. b) Dual Solenoid Valves these spool and sleeve type solenoid valves are momentary contact type. When one coil is energised, one inlet is connected to one outlet, with the other inlet/outlet connection connected to an exhaust port, when the coil is de-energised and other coil energised, the action is reversed. These valves are for use on double acting cylinder applications. 40

41 MODES OF OPERTION / N/C Normally Closed Pneumatic way, normally closed, pressurise to open, de-pressurise to close with the aid of a return spring, having one inlet and one outlet connection. Can be direct acting air operated against a return spring. Note: These valves are operated via a 3 way solenoid valve which is always required. / N/O Normally Open Pneumatic way, normally open, pressurise to close, de-pressurise to open with the aid of a return spring, having one inlet and one outlet connection. Can be direct acting air operated against a return spring. Note: These valves are operated via a 3 way solenoid valve which is always required / N/C Normally Closed Motorised m way, normally closed, energise to open (slow opening) de-energise to close (quick closing) with one inlet and one outlet connection. Motor driven against a return spring. / N/O Normally Open Motorised m way, normally open, energise to close (slow closing) de-energise to open (quick opening). / N/C Normally Closed Manual Reset (Solenoid) These valves operate on the same principle as / N/C direct acting version except once the coil is energised the valve will not open until manually opened by either a lever or push reset device. / N/C Normally Closed Manual Reset (Motorised) m The operation is similar to / N/C Normally Closed Manual Reset (Solenoid) except, once the motor is energised the valve will not open till a manual reset/relay button is operated, either remote or integral to the actuator. General use is for both manual reset or safety systems where knowledge of an electrical failure is required. Keeping the World Flowing 4

43 SELING SOLUTIONS Nitrile (BunaN) (NBR) Trade Names: Chemigum Hycar (Zeo (Goodyear)n Chemical), Ny Syn (Copolymer), Paracril (Uniroyal), Krynac (Polysar), PerNitrilen (Mobay) This is the most widely used O-Ring elastomer. It has excellent resistance to petroleum products. Excellent compression set, tear and abrasion resistance. Suitable for air, oil, water, acetylene, kerosene, lime solutions, liquefied petroleum gases and turpentine. Nitrile / BunaN is lcon s preferred sealing solution unless otherwise stated. lcon recommends that Nitrile is used within the temperature range of -0 C to +80 C (4 F to 76 F). Please note Nitrile is not recommended for highly aromatic petroleum / gasoline s or acids. EPDM (EPR or EPDM) Excellent resistance to weathering and ozone, water and steam, with good performance in castor and some phosphate ester based fluids and poor on petroleum / gasoline. It s low and high temperature capabilities are good, having excellent resistance to set with good resilience, this low compression set provides a suitable solution for steam sealing. EPDM is suitable for temperatures above the Nitrile range. Ethylene-propylene is generally suitable for most photographic solutions as well as numerous chemical solutions. EPDM has served to replace the formerly used butyl. lcon recommends that EPDM is used within the temperature range of -0 C to +0 C (-8 F to +48 F). Please note EPDM should NEVER be used in contact with mineral based fluids or DI ester based lubricants, due to excessive swell and deterioration. When lubrication is required silicone grease or fluids should be used. *VITON (FPM FLUOROELSTOMER) It has high temperature capabilities, excellent resistance to hydraulic oils, petrol and many other chemicals. Viton O-Rings are used in automobile and other mechanical devices requiring maximum resistance to elevated temperature and to many functional fluids. Viton is a fluorocarbon elastomer. Primarily developed for handling hydrocarbons such as jet fuels, gasoline s, solvent, etc., which normally caused detrimental swelling to NBR. Viton has a high temperature range similar to ethylene propylene but is more resistant to dry heat. Viton has a rather wide range of chemical compatibility. lcon recommends that Viton is used within the temperature range of -0 C to +0 C (-4 F to +30 F). *Viton is a registered trademark of Du-Pont * PTFE / TEFLON PTFE is a fluorocarbon resin known as a disc sealing material solution where all other synthetic materials have failed. Rulon is a form of Teflon having fillers which have been added for improved mechanical properties. Teflon with fillers are considered more of a plastic than a resilient-type material. They are virtually unattacked by any fluid. PTFE provides sealing solutions for cryogenic and steam applications. lcon recommends that PTFE is used within the temperature range of -00 C to +80 C (-38 F to + 36 F). *TEFLON is a registered trademark of Du-Pont. It must be noted that PTFE sealing will allow slight let-by. Silicone This elastomer provides high and low temperature solutions under certain conditions for numerous applications (it must be noted that silicone is not suitable for steam applications). It can handle hydrogen peroxide and some acid solutions. Silicone s retention of properties at high temperatures is superior to other elastic materials. lcon recommends that Silicone is used within the temperature range of -6 C to +0 C (-8 F to +48 F). It must be noted that Silicone has poor tensile strength, tear resistance and abrasion resistance. Neoprene Neoprene is commonly used for refrigeration systems sealing as an external seal. Suitable for alcohol, mild acids, water, air, ammonia, argon gas and other gases. lcon recommends that Neoprene is used within the temperature range of -0 C to +90 C (-4 F to +94 F). Consideration lthough lcon state a temperature range for it s elastomers, limitations are also dependent on their specific function within the valve. n example of this would be with a diaphragm and an O-Ring at a low temperature, both will stiffen, however, the sealing capabilities of the diaphragm will be reduced but the O-Ring, of similar material, which stiffens at low temperature may still perform its sealing function. lcon recommend that temperatures down to -0 C (-4 F) can be considered tolerable. Elastomers such as low temperature EPDM must be selected for use below this temperature along with the application. These can extend the low limit to approximately minus -40 C (-40 F) depending on specific usage. Generally the upper temperature limit for elastomers is +00 C ( F). Viton and EPDM can support higher temperatures up to +0 C depending upon application. When applications arise that are below or above the temperature capabilities of lcon s elastomers we can provide PTFE / PCTFE sealing solutions. These unique chemical-resistant materials can be used from -00 C to +80 C (-38 F to +36 F) when used considering specific design constraints. Keeping the World Flowing 43
