Flanged gate valve with rising stem and hand wheel - UL/FM approved for fire protection applications to max. 70° C

AVK gate valves are designed with built-in safety in every detail. The wedge is fully vulcanized in a double bonding process with AVK’s own drinking water approved EPDM rubber compound which features a very low compression set resulting in an outstanding ability to regain the original shape after having been compressed. A replaceable stuffing box stem seal system, a high strength stem and a thorough corrosion protection safeguard the unmatched reliability.
