3-inch - 2500LB forged steel high-pressure flanged stop valve, high-pressure flanged stop valve

3-inch - 2500LB forged steel high-pressure flange stop valve body cover connection design form

I. Body cover bolt connection forged steel stop valve. Valves designed with this connection form use bolts to connect the valve body and valve cover, and adopt spiral wound gaskets for sealing. The advantage is that it is convenient for maintenance during use;

II. Body cover welding connection forged steel stop valve. Valves designed with this connection form have the valve body and valve cover fully welded for sealing. The advantage is no external leakage;
