Y-pattern piston check valve

Y-pattern piston check valve

Generally speaking, the piston check valve provides back flow control for piping systems. As a result, the piston check valve is classified to the “non slam” check valves. Or it can be said that the piston check valve is designed specifically for use on the discharge of reciprocating compressors or any service with pulsating flow, as well as being used successfully in non-reciprocating service. The Y-pattern is the specified type of the piston check valve. It holds a great popularity of applications resulting from the rugged design manufacturing under the several necessary professional tests.

Actually, the sizes available of the Y-pattern piston check valve are in a wide range. And the pressure rating differ in a specified range. In terms of the end connections, the threaded, socket welded, weld end and flanged connections are available. And the valve body is bonnetless under pressure, as well as the seal gasket. Besides, the non-rotating stem ensures no torsional load in packing. What else, the Y-pattern piston check valves are easy and rapid in-line repair.

Considering of the installation, the Y-pattern piston check valve should be checked for proper identification to ensure the valve is of the proper type, material, and is a suitable pressure class and temperature rating to satisfy the application requirements.
