2-Way True Union Ball Valve


  • EPDM seal and O-ring
  • Size:2″-10″
  • Operating temperature range: 41ºF to 122ºF
  • Pressure Rating for 1/2″ – 2″ valves: 200 psi @ 70ºF
  • Pressure Rating for 2-1/2″ – 4″: 150 PSI @ 70ºF

1、Simple structure, small size, small volume, lightweight, easy to install, suitable for large diameter valves.
2、Easy to open and close quickly, labor-saving, small fluid resistance, can often be operated.
3、Good sealing can be achieved under low pressure.
4、Good adjustment performance.
5、The effective circulation area of the valve seat channel is larger when fully open, and the fluid resistance is smaller.
6、The opening and closing torque are minimal and the operation is flexible and effortless.
7、Sealing surface materials are generally rubber and plastic, so the low pressure sealing performance is good.

1、Small operating pressure and temperature range.
2、The sealing is poor.
3.The installation needs to be mounted on the pipe together with the flange.

4.Stable air pressure required from air presses

The PVC Pneumatic Butterfly Valve is a valve that opens, closes, or regulates the flow of the medium with a reciprocal rotation of about 90° of the disc type opening and closing member.

The PVC Pneumatic Butterfly Valve is one of the most important valves in the automation of piping systems.
