Flanged gate valve with rising stem - UL/FM approved for fire protection applications to max. 70° C and 250 psi
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 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. With exchangeable stuffing box stem seal, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Features
- Wedge core in ductile iron, fully encapsulated in drinking water approved EPDM in a 2-step vulcanization process that leaves a very strong rubber-iron bond preventing corrosion underneath the rubber. No iron parts are exposed to the water
- Wedge shoes integrated in the rubber gives low operating torque
- Stem of high strength alu-bronze C63020
- 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
- Counterbored and hot melt sealed A4 stainless steel bonnet bolts encircled by the bonnet gasket to prevent contact with the water
- Full bore and clear way
- Lightweight flange design (DN80 and 200 full flange)
- Epoxy coating acc. to DIN 3476, red RAL 3000
- OS&Y stem design gives a clear, visual indication of the wedge position
