2.Main Material Applied for Pressure Sealing Bonnet Gate Valve
 

The open-close part name is gate,that this cast steel gate valve only can fully open or fully closed, they can not adjust the flow,the gate have two sealing face and the sealing face are wedge type,the gate also have two type according to interior structure,one is solid gate ,anther is flexible gate, the advantage of flexible gate is that it will not be stuck when being fastened between gate and seat. te maket of the flexible gate valve is bigger than other gate valves.

The difference between pressure seal gate valve and others cast steel gate valve depending on pressure from medium to finished the sealing of the valve stem .thus eliminate the medium leakage out .so they usually used on important place.

We can divided into two types according to structure of the gate, one type is wedge gate valve, anther type is flat gate valve,wedge gate valve is mean the sealing face of the gate is wedge type(it have angle between them),flat gate valve is mean the sealing face of the gate is parallel type,wedge gate valve must rely on exogenic action to mechanical seal,but flat gate valve can rely on pressure of the medium to seal. so teh wedge gate valve have the bigger market than flat gate valve.

Advantage for the pressure seal gate valve

All of the gate valve are full bore,so they have the very small fluid resistance and the sealing face is very resistant to shock and wear.

The flow of medium is not restricted when valves are installed in the pipeline.they have simple structure and have the short face to face.so the price is lower than ball valve.

The pressure seal gate valve usually used for the highest piping line,their characteristic are higher pressure can be

make a better sealing effect,so no any medium can leakage out from pressure seal gate valve on any time.

Matters needing attention during installation

The workers must clean up the impurities in the piping and valves before the gate valve installed on the piping line.
