GO PR-1 SERIES REGULATOR (PR1-1E11H5J111)

The PR-1 Series is a versatile specialty pressure reducing control valve designed to fulfill a wide range of needs in instrumentation sample systems and other applications such as semiconductor processing gases.

The many features of the PR-1 make it ideal for a wide range of applications controlling pressures at low to moderate flows in gas or liquid service. 316L stainless steel is used to facilitate welded connections.

Stainless steel caps and adjusting screws prevent atmospheric corrosion and maintain appearance. The internal body surface finish is less than 25 Ra as standard. This, coupled with electropolishing, allows easier cleaning and potentially less particle contamination in the flow stream.
