• No hollows or cavities where stagnant water might collect and cause contamination
• Stem of copper alloy C35330
• Gland-follower for re-tightening with three main O-rings
• Round bonnet gasket, fixed in a groove in the bonnet preventing it from being blown out in pressure surges
• Countersunk and hot melt sealed bonnet bolts in stainless steel, encircled by the bonnet gasket preventing contact with the water

Information

AVK gate valves are designed with built-in safety in every detail. The wedge is fully vulcanized with AVK’s own drinking water-approved EPDM rubber compound. It features outstanding durability due to the ability of the rubber to regain its original shape, the double bonding vulcanization process and the sturdy wedge design. With an exchangeable stuffing box stem seal, the high-strength stem and the thorough corrosion protection safeguard unmatched reliability.
