Integrated Stainless Steel Ball Valve

Integrated Stainless Steel Ball Valve Integrated stainless steel ball valve uses new sealing material as its valve seat. Compared with the ball valve with PTFE seat, the service life of an integrated stainless steel ball valve is higher by 3 times ~ 5 times. An integrated stainless steel ball valve has the advantages of reliable sealing, small friction force, heat resistance, corrosion resistance. The face to face dimension of the integrated ball valve coincides with the globe valve, plunger valve, and drain valve, which expands its application range. The integrated stainless steel ball valve is widely used in the petroleum, chemical industry, papermaking, and other industries, and can replace the globe valve, plunger valve, and drain valve.
