GO Regulator PR1

PR-1 Series
Adjustable Pressure Reducing Regulator

The PR-1 Series is a versatile pressure reducing
regulator designed to fulfill a wide range of needs in
instrumentation sample systems and other applications
such as semiconductor processing gases. 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 body material is used to facilitate welded connections. Stainless steel caps and adjusting screws prevent atmospheric corrosion and maintain appearance. Enhanced internal body surface finish of better than 25 Ra plus electropolishing allows easier cleaning and potentially less particle
contamination in the flow stream. Five different seat materials, three alternate orifice sizes and seven pressure control ranges with stainless
diaphragms off er the user a wide spectrum of capabilities for pressure control with inlet pressures up to 6000 psig and standard operating temperatures up
to 500° F (260° C).
