PTP Series 3-way PVC Ball Valves

Full Port with NPT or Glue Socket True Union Connections (1/2" to 2")
Manual and Actuated 3-way PVC ball Valves



The PTP Series 3-Way Ball Valves can be used for flow diverting, mixing, or on/off isolation. They will replace a Tee + 2 valve linkage assembly at reduced cost and space, along with shorter installation and maintenance time. The patented seat stop carrier allows for in-line microadjustment of the ball seating, and features o-ring cushioning to minimize wear and prevent seizing. The PTP also includes a patented DUAL BLOCKĀ® locking union nut system, which ensures the nuts are held in position even under severe service conditions such as high vibration or thermal expansion. Integral mounting flange and bracketing allows for direct actuation and simple support, while a locking handle can prevent improper positioning. PTP Series 3-Way Ball Valves are part of our complete range of valves and flow meters, engineered and manufactured to strict quality, performance, and dimensional standards.
