Flanged gate valve with post indicator flange for fire protection applications to max. 70°C/160°F, rated working pressure 250psi/17bar (DN 350-400 on UL: 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.

Features
- Integral wedge nut firmly fixed to the wedge prevents vibration
- Wedge fully vulcanized with EPDM rubber in a process that prevents creeping corrosion underneath the rubber
- Wedge sliding on guide rails gives smooth operation and low operating torque
- A large conical stem hole in the wedge ensures circulation and prevents stagnant water
- Stem of stainless steel AISI 304 with rolled threads (DN50-300) or high strength alu-bronze grade C63020 (DN350-400)
- Full circle thrust bearing keeps the stem firmly lined up and ensures low operating torque
- Stem sealing with an NBR wiper ring, two upper O-rings in a PA bearing, one lower O-ring and one O-ring gland seal
- Round bonnet gasket fixed in a recess to prevent blow-out
- Bonnet bolts in A4 stainless steel, counterbored, sealed with hot-melt and encircled by the bonnet gasket
- Full bore and clear way
- Fusion bonded epoxy coating blue RAL5017 in compliance with DIN 3476 part 1 and EN 14901
