PR3-Pressure Reducing Regulators

Introduction

Hikelok 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

Features

  • Compact

  • Designed to minimize contamination and provide accurate regulation of any corrosive, noncorrosive, or toxic gas

  • Brass model provides added economy for control of non-corrosive media

  • Metal-to-metal diaphragm to body seal ensures minimum inboard and outboard leakage

  • Convoluted diaphragm delivers excellent accuracy and long service life

  • Panel mounting is available

  • Maximum 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 rated

  • Leakage Internal: bubble-tight External: design to meet ≤ 2 x 10-8 atm cc/sec He

  • Operating 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

Advantages

  • Simple design

  • Relatively small size

  • Springs of various rate can be adjusted to provide different outlet pressures

More Options

  • Optional material 316 stainless steel, Alloy C-276, Alloy 400, brass
