Piston Check Valves - API 6D - SCV Valve, LLC

SCV Piston Check Valves are quiet operating valves that effectively prevent backflow. The flapperless design is gentle on the seat as the piston rises and lowers with increased and decreased flow rates. The SCV designs offers many features and options beneficial for oil, liquid gas, and liquid applications. piston check valve convalve(plate) What is a check valve?What is a check valve?Check valves are designed to prevent the reversal of flow in a piping system. These valves are activated by the flowing material in the pipeline. The pressure of the fluid passing through the system opens the valve, while any reversal of flow will close the valve.What is Piston Check Valve ? Piston Check valve Parts(plate) What is lift check valve?What is lift check valve?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. Installation is the same as for a lift check in that the flow must enter from under the seat.What is Piston Check Valve ? Piston Check valve Parts
