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.
