Gate valve with Supa Maxi™/PE pipe end, SDR17. For drinking water and neutral liquids to max. 20°C. The maximum working temperature is set according to the ISO9080 lifetime requirements for PE pipes, and is therefore not the max. temperature for the valve.

AVK gate valves with one Supa Maxi™ coupling end and one PE end offers a combination of two well-known designs ensuring a long lasting solution with ease of installation. The Supa Maxi™ end connects to any pipe material and the PE end enables direct welding into PE pipelines. The valve itself is of our standard gate valve design with a wedge fully vulcanized with AVK’s own drinking water approved EPDM rubber compound, triple safety stem sealing system and superior corrosion protection.

Variant 638/00-126
Connection: Supa Maxi™ Coupling
Material: Ductile Iron
DN: DN80 - DN300
PN: PN10
Closing direction: Clockwise to Close

Features

  • Fixed, integral wedge nut prevents vibration and ensures durability
  • Wedge fully vulcanized with drinking water approved EPDM rubber and equipped with wedge shoes to provide smooth operation
  • Large conical stem hole in the wedge prevents stagnant water
  • Wedge and body guide rails ensure stable operation
  • Stainless steel stem with wedge stop and rolled threads for high strength
  • Full circle 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 four NBR O-rings, and an EPDM rubber manchette
  • Round EPDM bonnet gasket fixed in a recess
  • Countersunk and sealed stainless steel bonnet bolts encircled by the bonnet gasket
  • Full bore
  • Low operating torque
  • Fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901, GSK approved
  • Supa Maxi coupling end: Patented SupaGrip™ sealing with bracket ensures full support of the gasket even at minimum pipe size. Full tensile strength on all pipes is ensured by two different metal grip segments - every other of brass for PE/PVC and of hardened stainless steel for hard surface pipes. Angular deflection ±4°. Drinking water approved EPDM rubber. Notice: Observe separate mounting instructions for installation.
  • PE pipe end: A standard PE pipe is pressed onto the grooved valve end, locked with a steel ring and sealed with a plastic shrink hose. A boltless, full bore tensile resistant connection stronger than the PE pipe itself.
