American standard power station gate valve structure characteristics
① Adopting flexible wedge gate, the closing torque is small and easy to seal, also will not cause wedge off easily when the temperature changes.
Adopting replaceable back seat structure, it can assistant the packing seal, and maintain easily.
② This valve adopts welded connected seat with simple technique.
③ The middle path of the valve is adopting self-sealing structure, which can seal more effectively.
④ The sealing face is welded with abrasion-proof material which can strengthen the sealing performance and lengthen the usage life.
