ASTM A351 CF3M Wafer Check Valve, API 594, 3 Inch, 300 LB

Product Name: ASTM A351 CF3M Dual Plate Check Valve
Design Standard: API 594
Body Material: ASTM A351 CF3M
Size: DN80, 3 Inch
Pressure: PN25, Class 300 LB
End Connection: Wafer

We are a specialized manufacturer of wafer check valves, featuring a unique design with a center vertical pin shaft. When the valve is open, the resultant force of the fluid acts on the center of the sealing face of the disc. The counter spring's support force is applied to the center of the disc surface, causing the root of the disc to open first. This design minimizes wear on the sealing surface, a common issue with traditional valves, and enhances the durability of the valve seal. The wafer check valve is an automatic valve that opens and closes in response to the flow of the medium, preventing reverse flow and ensuring efficient, reliable operation.
