Features

A heavy-duty WCB cast steel non-return valve with hard-faced seating, engineered for high-pressure backflow prevention in oil and steam applications.

✅Heavy-Duty WCB Construction: Manufactured from ASTM A216 WCB Cast Steel, offering high mechanical strength and impact resistance for heavy industrial loads.

✅Hard-Faced Seating: Sealing surfaces are often overlaid with Stellite or hard alloy to resist wear, galling, and erosion caused by high-velocity steam or abrasive fluids.

✅Bolted Bonnet Design: Features a secure bolted bonnet for easy maintenance and internal inspection without removing the entire valve body from the line.

✅Full Opening Disc: The swing mechanism moves completely out of the flow path, minimizing turbulence and ensuring efficient operation in high-volume systems.

✅High Pressure Capability: Designed to withstand high pressure ratings (Class 150/300/600), making it the standard choice for refineries, power plants, and petrochemical facilities.
