The RHPS PRSTC model spring-loaded, pressure-reducing regulators control gas and liquid pressures in sanitary systems for the pharmaceutical and biotech market. Inlet pressures as high as 230 psig (16 bar) can be controlled to outlet pressures ranging from 4.3 to 130 psig (0.3 to 9 bar). Operating temperature range is -31° to 284° F (-35° to 140° C). Three body sizes are available: 0.5, 1, and 1.5 inch, all with integral sanitary clamp end connections. Flow coefficients (Cv) are 0.70 (0.5 in), 1.95 (1 in), and 5.48 (1.5 in). Designed for clean service, regulator internal surfaces are finished to 16 μ-in (0.4 μm) Ra standard. Body and spring housing are of 316 L stainless steel construction. Diaphragm, seat, and O-rings are FDA-compliant EPDM. All regulators are 100% factory tested, ultrasonically degreased, and cleaned. Cleaning based on ASTM-G93 Level C/CGA 4.1 is available as an option.
