Resilient seat gate valve for water and neutral liquids. Temperature range: -10° C to +70° C. 10% solid matter.

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. 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. The triple safety stem sealing system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Features

  • Cap top as standard
  • Fixed, integral wedge nut prevents vibration and ensures durability
  • The ductile iron core is fully vulcanized with drinking water approved EPDM rubber, no iron parts are exposed to the medium and the excellent rubber vulcanization prevents creeping corrosion underneath the rubber
  • The wedge has a large through bore and as there are no hollows in the core, stagnant water or impurities cannot collect and cause contamination
  • Stainless steel stem with rolled threads for high strength
  • Full circle brass thrust collar provides fixation of the stem and low free running torques
  • Triple safety stem sealing with an NBR wiper ring, a polyamide bearing with two EPDM O-rings, and another EPDM O-ring on stem, which prevents leakage when exchanging stem seals under pressure
  • Round bonnet gasket fixed in a recess groove in bonnet preventing it from being blown out by pressure surges
  • Bonnet bolts encircled by the bonnet gasket to protect against contact with the fluid and against corrosion
