IntroductionHikelok PR3 series valve is a kind of valve that reduces the inlet pressure to a certain required outlet pressure through regulation, and makes the outlet pressure automatically keep stable by relying on the energy of the medium itself.The pressure reducing valve is designed for Laboratory and point-of-use gas systems sampling systems, zero, span and calibration analyzer gases,specialty and industrial gas cylinder regulator,chromatograph flame detector fuel supply
FeaturesCompactDesigned to minimize contamination and provide accurate regulation of any corrosive, noncorrosive, or toxic gasBrass model provides added economy for control of non-corrosive mediaMetal-to-metal diaphragm to body seal ensures minimum inboard and outboard leakageConvoluted diaphragm delivers excellent accuracy and long service lifePanel mounting is availableMaximum Inlet Pressure6000 psig (413bar)Outlet Pressure Ranges 0-250 psig (0-17.2 bar), 0-500 psig (0-34.4 bar), 0-1500 psig (0-103.4 bar), 0-2500 psig (0-172 bar)Design Proof Pressure 150% maximum ratedLeakage Internal: bubble-tight External: design to meet ≤ 2 x 10-8 atm cc/sec HeOperating Temperature PCTFE: -40°F to 176°F (-40°C to 80°C) PEEK: -40°F to 392°F (-40°C to 200°C) PI: -40°F to 500°F (-40°C to 260°C)Flow Capacity Cv = 0.06
