BT-WC Disc Check Valve – Wafer Type, PN40, AISI 316 / CF8M

The BT-WC Disc Check Valve is a compact, wafer-type valve engineered for backflow prevention in high-pressure industrial systems. Designed for installation between flanges, this valve supports pressure ratings up to PN40, making it suitable for demanding applications involving liquids, gases, and steam.

Built from robust AISI 316 and ASTM A351-CF8M stainless steel, the BT-WC ensures excellent corrosion resistance and extended durability in aggressive environments. Its streamlined design allows easy inline installation without altering the piping layout, and it’s ideal for limited space conditions.

Suitable for a wide range of industrial applications including chemical processing, water treatment, oil and gas systems, and general-purpose utility lines, the BT-WC disc check valve offers reliable, maintenance-free operation with minimal pressure loss and a quick closing mechanism to prevent flow reversal.
