Single Stage Piston Regulator

CAD Model


Description: The PR family of regulators offers relatively precise pressure regulation in a versatile, economical, miniature package. A wide selection of porting configurations and adjustment styles are available, offering design freedom.

Max Inlet Pressure Rating: This is a single stage regulator, and is ideal for applications with steady inlet pressures up to a maximum of 500 psig.

Outlet Pressure Range: Maximum outlet range 0-400 psi. Piston style regulators contain coil springs, and are especially well suited for applications requiring higher outlet pressures (minimum 10 psi).

Approximate Weight: 72g in brass and stainless steel and 33g in aluminum. Weight will vary slightly, depending on configuration.

Porting: Eight different porting configurations are available. See images above for more information.
This regulator is available in both Relieving and Non-Relieving configurations.

Mounting: All models are supplied with a 15/32-32 thread, with two 9/16″ hex nuts and 2 washers for panel mounting.

Seals: Silicone seals are available for the PR regulator, but they are not recommended.  Silicone may wear quicker as well as reduce performance.  If you require Silicone in your application, please contact us for further details.
