AVK GATE VALVE, FL/FL, OS&Y, UL/FM APPROVED, Class 150

ANSI B16.42, OL red handwheel, A4 bolts, SS stem, EPDM wedge rubber, brass stem nut, red coating

Light-weight-flanged gate valve, OS&Y, UL/FM approved for fire protection applications to max. 70°C and 250 psi

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 replaceable stuffing box stem seal system, a high strength stem and a thorough corrosion protection safeguard the unmatched reliability.

Variant 145/46-008
Connection: Flanged
Material: Ductile iron
DN: DN65 - DN200
PN: ANSI CL150
Closing direction: Clockwise to Close

Features

  • 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
  • Wedge shoes integrated in the rubber
  • Stem in stainless steel 304
  • Gland follower for re-tightening the stem seal with two or three main O-rings
  • 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
  • Lightweight flange design
  • Epoxy coating acc. to DIN 3476
  • OS&Y stem design gives a clear, visual indication of the wedge position
