Andy Hatton
National Sales Manager – Gas
PE ball valve DONKIN CERTUS™ for use in the isolation of gas services to domestic, commercial and industrial premises.
AVK has an extensive range of internationally approved PE ball valves, ranging from OD20 up to OD180mm. Made from high performance PE100 material AVK PE ball valves can be welded to all PE100 and PE80 pipes making the valve an integral part of the fully welded leak-free pipe system. Minimum full bore for all sizes ensures limited pressure drop and greater flow through the valve. All spigot ends can be delivered with double spigot length option, allowing for a second electro fusion weld if needed.
