The Beaver Small-Bore Swing Check Valve allows the pressure of fluid flow to swing the hinged disc open in the upstream direction. The disc closes once flow stops and remains shut against flow from the opposite direction, preventing any backflow.

The disc is the same size as the pipe bore to ensure continuous fluid flow while reducing turbulence and minimising pressure drop. The stainless steel body provides resistance to pressure, temperature, and corrosion in many water, oil, and gas applications.

Use this swing check valve to protect important equipment, such as control valves or strainers, from reverse flow damage. Integrate it in horizontal pipe layouts or vertical pipelines where the fluid travels from the bottom.
