Description

Product Detail:

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. 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.
Three different seat materials, three alternate orifice sizes and 7 pressure control ranges with INCONEL®
diaphragms offer 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).
