  • Nozzle-type check valve with piston
    Patent number: 9746091
    Abstract: An exercisable check valve having a fluid delivery test channel and piston closure is disclosed herein. A valve closure member stops flow through the valve in the presence of backwards pressure or when engaged by the piston. The valve may be tested by applying a pressure source to the fluid delivery test channel to cause the piston to engage the valve closure member and stop flow through the valve. A test rod may then be inserted into a test rod port to ensure the valve closure member is in the proper closed position. The check valve may also include a biasing element to bias the valve closure member to an open position and a drainage channel. The check valve may be used in any piping or valve system.
