Relatively precise pressure regulation is offered by the PR family of regulators in a miniature, economical and versatile package. A wide range of porting configurations and adjustment styles are available which offer freedom of design. These are constructed of 303 stainless steel, brass and aluminum, with seals of Viton, Buna-N, EDPM and silicone.

The single stage regulator is suitable for applications which have steady inlet pressures up to a maximum of 500 psig. The maximum outlet pressure range is 0-450 psi. Coil springs are contained in the piston style regulators which are particularly suited to applications needing higher outlet pressures (minimum 10 psi). They weigh approximately 72g in brass and stainless steel (303 and 316) and 33g in aluminum. The varying weight depends on the configuration. There are eight differing porting configurations available. Both relieving and non-relieving configurations are available for this regulator.
