BT-V3WC 3-Piece Disc Check Valve – PN40, CF8M, Threaded/Weld Ends

The BT-V3WC 3-Piece Disc Check Valve is a heavy-duty, compact non-return valve engineered for industrial systems requiring dependable backflow prevention under high pressure. Designed for PN40 (up to 40 bar) applications, this valve is constructed with a 3-piece body configuration, allowing for superior mechanical strength, quick access for maintenance, and long-term durability.

Manufactured from ASTM-A351-CF8M stainless steel, it provides excellent resistance to corrosion and elevated temperatures, making it suitable for aggressive fluids and harsh operating environments. The disc-style closure mechanism delivers swift and efficient shut-off when flow reverses, protecting equipment and maintaining process integrity.

The valve is offered with a variety of end connection types, including threaded, butt weld, and socket weld, giving installers flexible options across different system designs. Compact and highly serviceable, the BT-V3WC is ideal for use in chemical processing, steam lines, compressed air systems, and other high-performance flow applications.
