Adjustable Pressure Control Regulator
nnpressure regulators The PR-1 Series is a versatile specialty pressure reducing control regulator designed to ful ll 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 ows in gas or liquid service. 316L material is used to facilitate welded connections. Stainless steel caps and adjusting screws prevent atmospheric corrosion and maintain appearance. Enhanced internal body surface nish of better than 25 Ra plus electropolishing allows easier cleaning and potentially less particle contamination in the ow stream.Six di erent seat materials, three alternate ori ce sizes and eight pressure control ranges with stainless diaphragms o er the user a wide spectrum of capabilities for pressure control with inlet pressures up to 6,000 psig and standard operating temperatures up to 500 F (260а C). >
* Replaces the LPR and MR Series.
