Polypropylene Socket Fusion Ball Valves
Aquatherm LP has begun stocking a standard PP ball valve with socket fusion connections, and without the true union adapters. The valves are manufactured by Red-White Valve Corp. and carry the necessary listings/certifications for the North American market. The valve and cartridge bodies are polypropylene, seats are PTFE, O-rings are NBR and the ball is Cr-plated DZR lead-free brass. Aquatherm part numbers for these valves are given in Table 1.
