STRUCTURAL FEATURES

1. Integral Valve Structure
It is welded by forged steel. The forging materials are subjected to ultrasonic examination according to ASME nondestructive flaw detection requirements. The welding slope on the connection face is subjected to liquid penetration examination.

2.Trunnion mounted ball valves

The ball is fixed and the seat rings are floating,free to move along the valve axis,side load generated by pressure acting on the ball is absorbed by bearing,at low pressure the seat sealing acting is achieved by the thrust of the springs acting on the seat.As the pressure increases the fluid pressure pushes the seat rings against the ball,making the sealing more reliable.

3. Extension Stem for underground
As for the fully welded ball valves with extended stem, the extension stem can be supplied if ground operation is needed. The extension stem is composed of stem, sealant injection valve, and drainage valve that can be extended to the top for the convenience of operation.
