27th Edition RHFS Product Guide - Ryan Herco Flow Solutions

BACK PRESSURE REGULATORSFEATURES• The back pressure regulator is designed toprotect piping and equipment from pressurechanges where a constant regulated pressureon the up stream side of the valve is required.• Prevents pumps from dead heading, overpressurization, pressure surge conditions,and maintains back pressure in closed loopsystems.• Adjustable screw and lock-nut makes it easy toaccurately preset desired up-stream pressure.• Teflon (primary) and EPDM (back-up)diaphragms standard.• No metal contact with fluid.• Wide adjustable pressure range (10-125 PSI).• Small pressure differential band from crackingpoint to fully open, and from fully open to close.• Top entry makes in-line maintenance quick andeasy.• Ideal for DI water, harsh chemical, and otherhigh purity applications.SPECIFICATIONS• Upstream pressure: vacuum to 150 PSI.• Regulated pressure:1/4” to 3/4” – 10-125 PSI.1” – 100 PSI1-1/2” to 2” – 10-60 PSI• Differential pressure:±3 PSI from set pressure relief point.• Available in PVC, Polypro, and PVDF.• Viton seals standard; EPDM and Kalrezoptional.• Valve ports:1/4” to 1” FNPT1-1/2” to 2” MPT• All valves fully ported.• Teflon diaphragm with EPDM back-up.ALSO AVAILABLEHI-PURITY TEFLONContact RHFS fordetails at 1-800-848-1141.ORDER INFORMATIONBACK PRESSURE REGULATORSize No. 002 005 007 010 015 020Nominal Size (in.) 1/4 1/2 3/4 1 1-1/2 2Part No. Material5465 PVC $226.00 $240.00 $303.00 $351.00 $472.00 $515.005466 Polypro 262.00 276.00 341.00 430.00 672.00 866.005468 PVDF 499.00 617.00 769.00 956.00 1,689.00 2,239.00300.110.220-240DIAPHRAGM PRESSURE REGULATORSALSO AVAILABLETEFLONAlso available in Teflon.Contact RHFS fordetails at 1-800-848-1141.FEATURES• The diaphragm pressure regulator is designedto be more sensitive to pressure changes whileprotecting piping systems.• This pressure reducing valve is designed toprovide excellent flow ratios over a wide pressurerange.• Teflon (primary) and EPDM (back-up)diaphragms are ideal for DI water or other ultrapure applications.• Adjustable screw and lock-nut makes presetdownstream pressure more precise andaccurate.• Wide working pressure range (5 to 100 PSIG).• This compact pressure reducing valve isdesigned to keep the stainless steel springtotally isolated from the fluid chamber insuringno metal contact with the fluid.ORDER INFORMATIONDIAPHRAGM PRESSURE REGULATOR• Top entry and parallel inlet and outlet ports tofacilitate installation and avoid piping problems.• Ideally suitable for most harsh chemicals, DIwater, and other high purity applications.SPECIFICATIONS• Upstream pressure: vacuum to 150 PSI.• Regulated pressure:5-100 PSI.1 to 100 PSI (1” only)• Available in PVC, Polypro, PVDF, and Teflon.• Viton seals standard; EPDM and Kalrezoptional.• Valve ports:1/4” to 1” FNPT1-1/2” to 2” MPT• All valves fully ported.• Teflon diaphragm with EPDM back-up.Size No. 002 005 007 010 015 020Nominal Size (in.) 1/4 1/2 3/4 1 1-1/2 2Part No.Material5470 PVC $322.00 $341.00 $497.00 $646.00 $788.00 $965.005471 Polypro 395.00 419.00 541.00 709.00 877.00 1,063.005472 PVDF 740.00 931.00 1,144.00 1,378.00 1,796.00 2,290.00300.110.250-2701-800-848-1141www.rhfs.com271
