POM service connection valve with AVK bonnet and PRK couplings for PE pipes. For drinking water and neutral liquids to max. 20°C. Note: 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 resilient seated service connection valves are designed with built-in safety in every detail. The wedge is 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 corrosion free materials and the high strength stem safeguard the unmatched reliability.

Variant 16/90-010
Connection: PRK Coupling for PE Pipe
Material: Polyoxymethylene (POM)
DN: DN25 - DN50
PN: PN16
Closing direction: Clockwise to Close

Features

  • Friction welded body, bonnet and end adaptors of POM (Polyoxymethylene)
  • Wedge of brass CW626N vulcanized with EPDM rubber – both brass and rubber certified for use in contact with drinking water– and shaped with guides and a special rubber profile ensuring low closing torques
  • Stem of stainless steel with rolled threads providing high strength
  • Stem sealing with NBR wiper ring and two EPDM O-rings
  • Friction ring between bonnet and thrust collar and a notch in the stem prevent overtorque of the valve
  • PRK coupling of POM in DN25-40 and of brass in DN50, fitted with a brass friction ring
