The rugged, true-union valves are available in PVC, CPVC, PVDF and polypropylene. Standard seals are EPDM or FKM (Viton), and PTFE seats. The new sizes complement the original True Blue Ball Valve line of 1/2” through 2” valves. Piping connections are offered for socket or threaded installation. Actuation packages are also available.
