Elite Flow Control’s Casting PSB Check Valves are high-performance, swing-type non-return valves engineered specifically for high-pressure service applications. Featuring a Pressure Seal Bonnet design, these valves provide a superior seal that actually improves with increasing line pressure – making them the preferred choice for demanding, high-integrity piping systems.
The non-penetrating disc shaft ensures the valve disc opens fully, minimising flow restriction and pressure drop across the valve. The seat surface can be hardened to significantly enhance wear resistance, extending operational life in tough service conditions.
Designed for both horizontal and vertical installation, and available with flanged or butt weld end connections, these valves offer exceptional flexibility for a wide range of plant configurations. Constructed from a comprehensive range of ASTM-standard materials including carbon steel, low-temperature carbon steel, stainless steel, and duplex stainless steel, they are suitable for service across Oil & Gas, Petrochemical, Power Generation, and allied industries.
