FISHER Control Valve

The self-aligning valve seat ring and the sturdy valve core both offer a tight shut-off performance whether for forward flow or reverse flow. 

The integrated valve body flange can be compatible with many different types of pipe flanges, meeting various pipeline requirements. 

The streamlined channels, sturdy and durable components, and a wide range of erosion-resistant inner material options all contribute to the valve's long and reliable service life in corrosive media environments. 

The eccentric valve core reduces the contact friction with the valve seat ring during opening, thereby minimizing the wear of the valve seat. 

The selection of valve internals materials and the coating of the valve body help to withstand oil sands, supply to furnaces and other highly corrosive applications. 

The sturdy and durable metal or VTC valve seat ring and valve core can tightly cut off the fluid, while the valve core rod does not deform and no thinner sealing ring is required. 

Before tightening the retaining ring, there is no need to perform special positioning, clamping or separate centering of the valve core and valve seat ring. This improves the accuracy of alignment and the convenience of assembly.
