Q641 pneumatic ball valve

This ball valve mainly used for cutting off or connecting media of pipes, also be used for regulating and controlling fluid. Compared with other valves, is contain some features

1、  small fluid resistance

2、  thrust bearing reduce friction torque of valve stem, make valve stem work quiectly and flexibility 

3、  good sealing of valve seat, use PTFE sealing ring, easy to seal, and sealing ability of valve increased by media pressure

4、  reliable sealing of valve stem

5、  good smooth of PTFE, small loss of friction with sphere, so long using life with ball valve
