AVK FLANGED GATE VALVE, UL/FM APPROVED, 250 PSI

Description

Key Features

• A large through bore in the wedge eliminates collection of stagnant water which might cause contamination
• Wedge shoes integrated in the rubber
• Stainless steel stem with rolled threads for high strength
• Stem seal with one lower main O-ring backed up by two upper O-rings in a polyamide bearing replaceable under pressure
• Round bonnet gasket, fixed in a groove in the bonnet preventing it from being blown out in pressure surges
• Countersunk and hot melt sealed bonnet bolts in stainless steel, encircled by the bonnet gasket preventing contact with the water
• Full bore and clear way
• Low operating torque
• Epoxy coating acc. to DIN30677 and AVK guidelines, RAL 5017

Information

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.
