API 594 Wafer Check Valve, ASTM A351 CF8M, 12 Inch, 150 LB

Key Specifications / Features

This API 594 Wafer Check Valve features a dual plate structure and is crafted from stainless steel ASTM A351 CF8M for superior corrosion resistance. Designed for 12-inch (DN300) pipelines, it operates at Class 150 LB (PN20) pressure, ensuring reliable backflow prevention and compact installation in various industrial applications.

We are a specialized manufacturer of wafer check valves. These valves feature a center vertical pin shaft design. When the valve opens, the fluid's resultant force acts on the center of the disc's sealing face, while the counter spring support force is applied at the disc's center. This design ensures that the root of the disc opens first, reducing wear on the sealing surface compared to traditional valves. This increases the durability of the valve's seal. The wafer check valve automatically opens and closes with the flow of the medium, preventing reverse flow.
