The mechanical partsof the valve are isolated from theprocess fluid.• George Fischer pressureregulating valves can handle awide range of flow and pressurecontrol applications.• NOTE: HP cleaning and baggingavailable on request.APPLICATIONS• Biotechnical.• Beverages.• Chemicals.• Cosmetics.• Pharmaceuticals.• Electronics.• Food Processing.• Pollution Control.• Semi-conductor.• Water Supply and Sewage.Choice of three styles of +GF+pressure control valves:• Type V182 pressure regulatingvalve.• Type V185 pressure relief valve.• Type V186 back pressure regulatingvalve.PRESSURE RELIEF VALVESGeorge Fischer type V185 pressure relief valvesmay be used in pipelines where no greater pressurethan the set line pressure is desired.TYPE V185 PRESSURE RELIEF VALVE- servesto keep system pressure constant, to balance ourpressure pulsation and to reduce pressure peaksin process systems.PRESSURE DIFFERENTIAL BETWEEN INLETAND OUTLETMinimum 14 PSI/ 1 barFEATURES• Relieves excess pressure in apiping system.• Provides highly accurate andstable pressure control.• Dimension range 1/2” - 2” (20 mm- 63 mm).• Molded PVC, Polypropylene, andPVDF bodies.• Diaphragms and seals in EPDMand PTFE.• FNPT, spigot, flange, IR Plus,socket union, or BCF endconnections.• The valve operates when the setline pressure is exceeded by 10%.The excess liquid is dischargedthrough the branch. The valveis adjusted by a set screw andsecured with a locknut.• No dead space in valve body.• Mechanical parts are isolated fromthe process fluid.• Seals and diaphragms are EPDMor PTFE. Combinations and endconnections, other than thosebelow, may be available.• Thread insert on lower body formounting.SPECIFICATIONS• Temperature range:PVC: 32°F – 140°/0°C – 60°C.PP: -4°F – 176°F/-20°C – 80°C.PVDF: -4°F – 248°F/20°C – 120°C.• Adjustment range: 1.5 - 135 PSI.300.140.110 PVC300.140.200 PP300.140.140 HP BCF PVDFORDER INFORMATION:5670.(Size No.) PVC/EPDM FNPT Connection5675.(Size No.) PP/EPDM IR Plus Connection5677.(Size No.) PVDF/PTFE IR Plus/BCF Plus ConnectionNominalSize(in.)NominalSize(mm.)PressureSet RangePSI5670PVC5675PP5677PVDFSizeNo.Type105 1/2 20 V185 7-150 $250.83 $297.50 $887.83107 3/4 25 V185 7-150 283.50 332.50 1,037.17110 1 32 V185 7-150 309.17 379.17 1,085.00115 1-1/2 50 V185 7-150 399.00 490.00 2,515.33120 2 63 V185 7-150 539.00 530.83 3,371.67262
