Dual Plate Check Valve

Ideal for service and installation in tight spaces with horizontal or vertical (flow up) pipework.

Dual Plate, Dual Disc or Twin Plate Check Valves are a Wafer pattern, fast acting and self-actuated (or automatic) Non-Return Valve. Suitable for a range of liquids and gaseous fluids, free of solids they can be used in applications from Fire Protection and Chemical Plants to Potable Water and Low-Pressure Gas service.

With a short face to face dimension, the Dual Plate Check Valves are designed to suit EN1092-2 PN10 – 16 or ANSI B16.1 flanges and Grooved End IPS connections. A fully Lugged design is also available for larger sized valves. The short face to face design is light weight and ideal for service and installation in tight spaces with horizontal or vertical (flow up) pipework.

Dual Plate type check valves feature a spring assisted, short stroke Dual Disc action for improved dynamic behaviour which reacts quickly to Deceleration Rates. The valve is closed in a fraction of a second, reducing Water Hammer and minimising Surge pressures helping to protect expensive pumping equipment and pipework.

Valve sizes range from DN50 (2″) to DN1500 (60″), pressures up to 20.7 Bar (300 psi) and temperatures up to 150°C (302°F). Meeting stringent design standards, valves can be supplied with approvals from FM, UL (Underwriters Laboratories), DWI (Drinking Water Inspectorate), WRAS (Water Regulations Advisory Scheme) and WIMES (Water Industry Mechanical & Electrical Specifications 8.09 i1).
