Light-weight-flanged gate valve, NRS, 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 triple stem seal system, a high strength stem and a thorough corrosion protection safeguard the unmatched reliability.

Variant 145/40-007
Connection: Flanged
Material: Ductile iron
DN: DN65 - DN200
PN: ANSI CL150
Closing direction: Clockwise to Close

Features

  • 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
  • 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 high grade A4 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 3000, acc. to DIN 3476
