Frequently Asked Questions

What is a SHARPE piston check valve used for?

A SHARPE piston check valve prevents backflow in piping systems by using a spring-loaded piston that closes when flow reverses. It is commonly used in industrial water, oil, and gas applications where reliable one-way flow control is needed in stainless steel inline installations.

What are the specifications of the SHARPE piston check valve MPN 4371001550?

The SHARPE piston check valve MPN 4371001550 has a 1 1/2 inch pipe size with FNPT x FNPT female NPT connections. It features a stainless steel inline valve body and a piston design for positive sealing. This model is suitable for moderate-pressure industrial systems.

How to install a SHARPE piston check valve?
