The Non-Return Valve Class 900, Swing Type with Bolted Cover, is engineered for high-pressure applications where secure, one-way flow is essential. Built with robust materials such as WCB, CF8M, or SS 316, this valve is ideal for oil & gas, power generation, petrochemical, and industrial steam systems.
The swing-type disc ensures smooth forward flow and immediate closure during reverse flow, protecting pumps and equipment from damage. The bolted cover design allows for easy maintenance while ensuring leak-proof sealing under extreme pressures.
Key Features:
Pressure Rating: Class 900
Design Type: Swing Type Non-Return (NRV)
Body Materials: WCB, CF8M, SS 316
End Connection: Flanged (ANSI B16.5)
Cover Type: Bolted Cover
Standards: API 6D / ASME B16.34 / API 594
Applications: Oil & Gas, Power Plants, High-Pressure Steam, Chemicals
Leakage Class: Class VI
Temperature Range: Upto 425°C (based on material selection)
Built for strength and dependability, the Class 900 Swing Type Non-Return Valve ensures efficient backflow prevention in the most demanding environments.
