AVK GATE VALVE, FLANGED, NRS, UL/FM APPROVED, 250 PSI
Flanged gate valve with wrench nut - 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 triple stem seal system, a high strength stem and a thorough corrosion protection safeguard the unmatched reliability.

產品特點
- Fixed, integral wedge nut prevents vibration
- Wedge core in ductile iron, fully encapsulated in drinking water approved EPDM in a 2-step vulcanization process that leaves a very strong rubber-iron bond preventing corrosion underneath the rubber. No iron parts are exposed to the water
- 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
- Counterbored 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
- Fusion bonded epoxy coating, RAL 5017, acc. to DIN 3476
