Resilient seated gate valve for water and other neutral liquids, including treated waste water free of solids and fibrous impurities to max. 70°C
AVK series 21 gate valves are designed to BS 5163 and come with built-in safety in every detail. The wedge is fully vulcanized with AVK’s own drinking water approved EPDM rubber compound. It features an outstanding durability due to the ability of the rubber to regain its original shape, the double bonding vulcanization process and the sturdy wedge design. The triple safety stem sealing system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Features
- Wedge nut is made of high strength Si-brass, designed as a fixed, integral part of the wedge which prevents vibration and ensures durability
- Full circle thrust collar keeps the stem firmly lined up and ensures low operating torque
- Wedge core fully vulcanized with drinking water approved EPDM rubber in a process that eliminates creeping corrosion underneath the rubber
- A large conical stem hole going all the way through the wedge ensures circulation and prevents stagnant water
- Triple safety stem seal with an NBR wiper ring outermost to protect against contamination from outside, in the middle two O-rings around the replaceable radial bearing, and innermost an O-ring is the main seal to the system pressure
- Wedge shoes in PA and guide rails on the body make the wedge slide easily up and down regardless of differential pressure
- Stem in stainless steel with wedge stop and rolled threads for high strength
- Bonnet gasket in EPDM with a circular cross-section, fixed in a recess to avoid blow-out
- Counterbored stainless steel, A2 bonnet bolts, sealed with hot-melt and encircled by the bonnet gasket
- 250µm blue epoxy (WRAS) coating
