Product Description
300LB LCC Bolted Bonnet Piston Check Valve
A piston check valve is essentially a lift check valve. It has a dash-pot consisting of a piston and cylinder that provides a cushioning effect during operation. Because of the similarity in design to lift check valves, the flow characteristics through a piston check valve are essentially the same as through a lift check valve.
The valve's top-entry design allows for easy access and replacement of all valve internal parts with reduced downtime.
