Resilient seat gate valve for fire applications and drinking water to max. 70°C, pressure rating UL: 200 psi, pressure rating AWWA C515 and FM: 250 psi
AVK gate valves are designed with built-in safety in every detail. The wedge is fully vulcanized with AVK's own EPDM rubber compound with multiple drinking water approvals. 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. A triple stem sealing system, a high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Features
- Fixed, integral wedge nut prevents vibration
- Polyamide wedge shoes protect the wedge rubber and provide low operating torque
- AISI 316 stainless steel stem, bronze wedge nut and A4 fasteners for high corrosion resistance
- A large conical stem hole in the wedge prevents stagnant water from accumulating inside the valve
- Three independent stem seals: outermost a wiper ring protects against pollution entering from the environment, it is backed up by the two O-rings surrounding the radial bearing and innermost a separate O-ring creates the main hydraulic seal to the flow
- Thust bearing consisting of a total of 8 stainless steel-discs coated with a low friction, self-lubricating bronze-PTFE composite
- Round NBR bonnet gasket fixed in a recess to avoid blow out
- Counterbored stainless steel bonnet bolts encircled by the bonnet gasket and sealed with hot-melt glue
- Post indicator flange
- Integrated lifting eyes for easy handling
- Fusion bonded epoxy coating, red RAL 3000, drinking water approved
