1.Anti-fire safe design.Anti-static device
2.Free leakage of body Sealed construction

4.Extension stem.

1.Extension stem

For the underground installed valve,the stem can be lengthened and for the convenience of operation the corresponding compound injection nozzle and drainage valve can be extended to the top of valve.

When the body pressure going up un-normally as the unstable factor,the trunnion ball valve downstream seat will be pushed by un-normally pressure,and the release theunnormal pressure automatically,it doesn't damage to the sealing of upstream seat.

3.Anti-static device

In order to prevent friction among ball,stem and PTFE that generates static electricity which may light the combustibles and explosives that cause an accident,in this ball valve,static-conduction spring is set between the stem and the ball,the stem and the body.Thus static electricity is conducted to ground and system safety is secured.
