AVK GATE VALVE, FLANGED, AWWA, PN10/16
Brass/alu-bronze stem, OS&Y, handwheel, EPDM (NBR gasket), A4 bolts, brass wedge nut, 250 µm red EP, UL/ULC/FM
Flanged gate valve with rising stem OS&Y for fire protection applications to max. 70°C/160°F, rated working pressure DN 50-300: 250psi/17bar, DN 350-400: 200psi/14bar
AVK series 45 gate valves are designed to US-standards. Valve body, bonnet and wedge core are made of ductile iron which ensures high strength and reliability. The wedge is fully vulcanized with AVK's own drinking water approved EPDM rubber compound featuring an outstanding ability to regain its original shape. Corrosion protection is excellent with all iron parts coated with fusion bonded epoxy, fasteners in stainless steel and stem in either copper alloy or stainless steel.
