About Cast Steel Wafer Check Valve
The Premier Valves Cast Steel Wafer Check Valve is engineered for efficient non-return flow applications, ensuring reliable prevention of backflow in pipelines across industries such as petrochemical, oil & gas, water treatment, and power generation. With a swing type design and lifting bolt for easy installation, this compact and lightweight valve is perfect for tight-space applications.
Compliant with API 6D design and API 598 testing standards, the valve is precision-engineered for long-term performance and durability. Built as per ASME B16.10 face-to-face standards, it fits seamlessly into existing pipeline layouts with wafer end connections to suit ASME B16.5 flanges.
Available in ANSI Class 150# and 300#, the valve covers a wide range of pressure requirements and comes in sizes ranging from 50 mm to 600 mm. Its construction uses high-grade materials such as WCB, CF8, CF8M, Hastelloy, Super Duplex, Alloy 20, and LCB for both the body and disc, offering excellent resistance to corrosion and wear.
The seat materials include EPDM, Nitrile, PTFE, and Viton, ensuring tight shutoff and chemical compatibility for diverse service conditions. With automatic operation, the wafer check valve offers maintenance-free, efficient, and dependable service in horizontal and vertical installations.
