BT-PC Piston Check Valve – PN40, Threaded Ends, CF8M Stainless Steel

The BT-PC Piston Check Valve is a robust non-return valve engineered for high-pressure applications where backflow prevention is critical. Rated for PN40 (40 bar) pressure and temperatures up to 230°C, this valve ensures safe and efficient operation in steam, water, gas, and industrial fluid systems.

Built from ASTM-A351-CF8M stainless steel, the valve offers excellent resistance to corrosion and mechanical stress, making it ideal for chemically aggressive or thermally demanding environments. The internal spring-loaded piston mechanism responds quickly to pressure changes, allowing unidirectional flow while preventing reverse flow when the system shuts down or pressure drops.

Its threaded connections ensure quick and secure installation, while the DIN 3202 Part 4 M8 compliant body ensures dimensional consistency and compatibility with European piping layouts.

The BT-PC valve provides reliable sealing and long-term durability, making it a trusted solution for both horizontal and vertical installations where space and performance are at a premium.
