750 one-way pressure relief and vacuum relief valves

Product description:

The 750RP pressure relief and 750RV vacuum relief valves are designed for high precision applications requiring exact automatic pressure or vacuum relief over a wide range of pressure differentials.

These valves are used in a variety of applications including medical and surgical equipment, aircraft electronics, and other applications.

The valves may be clamped in a 9/16 inch (14.3 mm) UN-2B threaded hole where the minimum wall thickness in 1/16 inch.
