5 Quality is a rule of conduct in our supply chain Safety comes first, especially for AVK For more than 0 years, AVK has successfully been meeting the strict safety demands of natural gas companies. AVK valves are manufactured in modern factories characterized by streamlined flows and a high degree of automation. We are entirely committed to ensuring that quality remains a naturally integrated part of our production flow. Throughout the processes, a number of tests are carried out to safeguard the traceability, durability and operational reliability of our products. Our quality assurance system is of course certified according to ISO 900. AVK gas valves in Denmark HMN Naturgas (covering Central/Northern Jutland and the Copenhagen area) installed the first AVK valves in the early eighties, when the natural gas distribution was established in Denmark. Thus, we have co-operated with AVK for more than 5 years, and the first valves installed are still in service. AVK has always provided a good service and products of high quality.

6 The unique wedge is the heart of our gate valves Unique features and benefits: Fixed, integral wedge nut sealed with rubber prevents corrosion (). Double bonding vulcanization process ensures maximum adhesion of the rubber. Guide rails with integrated wedge shoes ensure low friction and smooth operation (). Rubber vulcanized to the core with min..5 mm on all pressure bearing surfaces and mm on all sealing surfaces gives optimum corrosion protection. Large rubber volume in the sealing area provides optimum sealing (). Large plain and conical stem hole () prevents stagnant water and accumulation of impurities. AVK s own rubber compound features an outstanding compression set ensuring tight sealing even after having been compressed numerous times. 6 Valves and accessories for gas

7 Our rubber compound features excellent compression set and bonding State-of-the-art rubber technology AVK GUMMI A/S develops and manufactures the rubber compound for wedges and gaskets using highly advanced technologies. Data is collected throughout the entire manufacturing process which secures traceability of every individual ingredient, each compound and the finalized components. AVK GUMMI makes a number of tests to ensure that the compression set values, the adhesion and the tensile strength meet the predefined requirements. The NBR compound NGW-70 is approved according to EN 68. Excellent ability to regain original shape AVK GUMMI A/S has a profound knowledge of a rubber s compression set, meaning its ability to regain original shape. Even after many years of service where the wedge rubber has been compressed numerous times, the rubber will regain its original shape and ensure a tight sealing. Impurities will not affect the rubber surface or the tightness of the valve, as the impurities will be absorbed in the rubber when the valve is in closed position. The wedge core is immersed in two different baths to provide ultimate bonding between core and rubber. As a result, we can offer the best possible rubber adhesion and corrosion protection of the wedge. Valves and accessories for gas 7

8 Polished stems with rolled threads prevent leakages Stainless steel stems with wedge stop The wedge stop provides a firm stop against the wedge nut when opening the valve. This prevents the wedge from compressing the stem seals and from damaging the coating inside the bonnet resulting in prolonged durability of the valve. The stem threads are rolled in a cold pressing process which maintains the steel structure and increases the strength of the stem. This method results in smooth thread surfaces and brings about low operating torques and prolonged durability. Finally, we polish the stems to provide a completely even interface between the stem and the stem nut without risk of leakages. 8 Valves and accessories for gas

9 No compromise on tightness and traceability Triple safety in the stem sealing system An NBR wiper ring protects against impurities from the outside. Tightness and low friction are provided by four NBR O-rings in a stem seal nut, which is replaceable under pressure. An NBR manchette is the main seal to the flow and prevents leakage in the rare case that the stem seal nut needs to be replaced. Tight assembly of valve body and bonnet An NBR bonnet gasket fits into a recess between the valve body and the bonnet. The stainless steel bonnet bolts are encircled by the bonnet gasket, countersunk in the bonnet and finally sealed to prevent corrosion. Full bore prevents pressure loss A full bore with the same nominal diameter as the pipeline ensures minimum pressure loss, as the valve does not cause any reduction in the flow path. 00 % pressure test and traceability Every single valve is pressure tested to DIN 0-5, PG / EN 77 class before leaving the factory. In open position: 0.5 bar with air.5 X PN with water. X PN with air, from both sides In closed position: 0.5 bar with air. X PN with air, from both sides When the valve has successfully passed the pressure test, the date and serial number are stamped on the valve stem and noted in the pressure test report for documentation.

10 Corrosion protection in compliance with GSK requirements Internal and external epoxy coating according to DIN and GSK All castings are blast cleaned according to ISO 9-. Any unevenness of the product surface is cleaned to provide perfect adhesion of the coating. The epoxy is applied electrostatically in a closed booth, either manually or in our automatic fluidized bed system, where the powder melts and cures in contact with the preheated component. Thorough control measures are applied to ensure optimum corrosion protection in accordance with DIN and GSK requirements. 0 Valves and accessories for gas

11 External PUR coating provides cathodic protection Galvanic corrosion prevention An effective method to avoid galvanic corrosion is to keep the pipe system shielded to avoid that pipes and shut-off valves are in direct contact with the surrounding soil. AVK offers gate valves effectively protected with a PUR coating of minimum.5 mm. Every single PUR coated valve is pinhole tested by means of a holiday detector with an output voltage of 0,000v. Our approval criterion is zero pinholes. Thorough tests of the epoxy coating We check each batch of epoxy coated components to ensure a layer thickness of minimum 50 μ and a pore-free surface. The impact resistance is tested by dropping a steel cylinder on the coating surface through a one meter long tube. Subsequently, no visible cracks or penetration of the coating are accepted. In addition to our own tests, the adhesion and cathodic disbonding of the epoxy coating are examined six times per year by the independent GSK authorities. Valves and accessories for gas

12 Gate valves with unique PE end connection Stronger than the PE pipe itself The DVGW approved class connection is stronger than the PE pipe itself. A piece of standard PE pipe is pressed directly onto the grooved valve end. The grooving combined with a sleeve around the valve/ pipe connection ensures that the PE pipe material is compressed into the grooves. This ensures that the connection remains tight and tensile resistant the entire service life of the pipeline. The connection is sealed with a shrink hose to provide corrosion protection. The full, straight bore ensures minimum pressure loss and makes underpressure drilling possible. Valves and accessories for gas

13 A natural part of PE pipe networks Direct welding into PE pipes The valves enable direct welding into PE pipes by using socket fusion or butt welding. The full, straight bore ensures minimum pressure loss and makes under pressure drilling possible. The valves are available with PE x PE connection and with flange x PE connection. Foundation provides stability Valves in DN can be equipped with a foundation that secures the stability of the valve and prevents opening or closing torques from being transferred to the PE pipe. The foundation is made of hot-galvanized steel and includes two plastic straps for fixation of the valve. Valves and accessories for gas

36 Synthetic surface boxes - a benefit to our users and the environment Why choose a synthetic surface box? Lightweight material; ensuring easy handling. Maintenance free; eliminating the need to clean or grease the metal seat to protect against corrosion or frost. Noiseless in traffic zones; providing noise absorption by its synthetic material. 00 % recyclable; requiring 80 % less resources throughout its complete life cycle compared to an iron surface box. Heat resistant up to 50ºC. Designed for tough conditions In collaboration with the Dutch Institute of Synthetic Materials (TNO), AVK has selected a PA based material for the surface boxes. The specially compounded PA resin is suitable for the load of road traffic during all seasons of the year. It especially enhances the resistance against high impact forces at low temperatures and offers sufficient heat resistance for safe installation in hot rolled tarmac. The ribs in the housing secure fixation in the road foundation. Floating surface boxes with great flexibility The deflection ability secures optimal fit on sloped surfaces. The internal fixation of telescopic extension spindles enables height adjustment after installation. The large chamber provides easy access for mounting and demounting of the extension spindle, and the closed design protects the extension spindle against impurities. The surface boxes are available with a square surface plate for pavements and with a round surface plate for other applications. The body is made of polyamide PA-6 and the surface plate and lid are of ductile iron with black primer. The lids are also available with yellow epoxy coating. The internal fixation of telescopic extension spindles enables height adjustment after installation. 6 Valves and accessories for gas

37 Wide range of surface boxes completes the AVK assortment Our Classic range - fixed or height adjustable The Classic surface boxes are DVGW approved and withstand maximum traffic loads according to DIN 07. The surface boxes are designed with a body of PA and a lid of cast iron with GAS inscription. They are available for gate valves and service connection valves, in fixed height and height adjustable designs, and optionally lockable or with locking clip on bolt for installation in places with fast heavy traffic. A height adjustable surface box is very easy to install. The 5º angle adjustment enables adaptation to the slope of the road, and the positioning of the top part is flexible by means of the O-ring. And last but not least, they do not require any expensive corrections after installation or renovation. Support tiles for Classic and Futura surface boxes A support tile increases the support surface in weak soils, secures center location of the extension spindle and prevents telescopic extension spindles from being pushed back. Our Futura range - featuring synthetic lids The Futura surface boxes feature a slim design with fixed height and a locking clip on the bolt to prevent the lid from being lifted off unintentionally. The surface boxes are available for gate valves and service connection valves, with round or square tops, and optionally lockable by a special key. Furthermore, there is a choice between a black cast iron lid, a yellow synthetic lid, and a black synthetic lid. All lids are with AVK and GAS inscription. Top frames provide extra support in soft soil. They are more visible and prevent possible damage to the surface box and extension spindle caused by vehicles. The synthetic lids are 00 % corrosion-resistant, contribute to further reducing the weight and will look nice even after years of use. Valves and accessories for gas 7

46 New range of PE 00 ball valves extends the valve package The PE 00 ball valves are produced with state-of-the-art machinery to guarantee a consistently high quality. We are able to trace the components throughout the manufacturing process from the initial injection moulding over machining and welding and to the final batch release test. Every valve is given a unique serial number which can be traced as far back as to the raw polyethylene material. The robust PE 00 ball valves have been extensively type tested against worldwide leading standards. They are DVGW approved, and we have carried out a number of additional tests exceeding the requirements specified in the standards. 6 Valves and accessories for gas

47 Proven design with integrated safety features Integrated safety features The groove () around the stem will adapt to any deformation as a result of upstream pressure on the ball when the valve is in closed position. The seat retainer () ensures that the ball seat is kept in place at all times, which guarantees a reliable function. Low operating torques The PE 00 ball surface combined with the high quality rubber seals and a special grease give low operating torques and prevent sticking. The expansion grooves (+) also contribute to low operating torques and eliminate the necessity of gearboxes. Safety connector prevents leaks If the valve is overtorqued during opening or closing, the connector is, as a safety feature, designed to break before the valve seals in order to prevent leakage. The safety connector is replaceable under pressure. Components adapt equally to the temperature Any differences in medium and surrounding temperatures may have an influence on the construction materials. PE 00 is used for the outer body, the ball and the seat retainer rings. This results in an equal distribution of expansion and shrinkage values on all components, and as a result their interfacing tolerances are maintained. Valves and accessories for gas 7

52 Centric butterfly valves for above ground installations Renowned butterfly design The butterfly valves are produced by Wouter Witzel EuroValve, a well-esteemed company in the AVK Group, and one of very few manufacturers of butterfly valves with fixed liner. The Wouter Witzel butterfly valves are approved by all major authorities such as KIWA, DVGW, SVGW, and WRC. Cost efficient installation The compact lightweight construction saves space and makes the valves easy to handle. The streamlined disc shape ensures minimum turbulence and head loss. Furthermore, the low torques facilitate the operation of the valves allowing the use of smaller and less expensive actuators. Outstanding seating concept The rubber is injection moulded directly on the valve body forming a permanent bond with an optimal rubber shore hardness. Consequently, there is no risk of deformation or dislocation of the liner making the valves suitable under vacuum conditions. The disc has a profiled sealing edge which requires minimal deformation of the liner to achieve a tight sealing. This gives less wear of the liner and low operating torques. Therefore, the butterfly valves are the ultimate choice for applications with high operation frequency. 5 Valves and accessories for gas

60 Stainless steel repair clamps for quick repair of leakages Cost-effective repair Our repair clamps are used worldwide for repair of leakages and ruptures in pipe systems. The design ensures a cost-effective and reliable solution for quick repairs of steel, cast iron, and ductile iron pipes. The repair clamps may be used for permanent repair of punctures as well as longitudinal and circumferential cracks. The functional principle of the repair clamp is based on a stainless steel, pre-rolled plate which is clamped around the pipe and fastened with lugs and nuts. The tensile force applied when fastening the clamp is converted to a radial grip on the rubber lining. Complete range of stainless steel clamps The range includes a single band clamp with diameters ranging from 8-5 mm to mm, a double band clamp ranging from 88-0 mm to mm, and a triple band clamp ranging from mm to mm. Other dimensions are available upon request. The clamps are available with or without BSP thread, in lengths of mm with intervals of 00 mm, and in stainless steel AISI 0 or AISI 6. They are designed with NBR rubber lining, teflon coated A bolts, and teflon coated A nuts. External clamps for DN 600 to 000 pipes are also part of the range. 60 Valves and accessories for gas
