Non-Return Valve, Dual Plate
We supply dual plate (duo-check) non-return valves in various sizes.
This valves are typically fitted to Hick Hargreaves packaged blower units.
As with all non-return valves, this valve is designed to allow product through the hinged panel in one direction but closes shut under gravity and lack of pressure to prevent product back-flow into the line and potentially into the blower.
