Low pressure line regulators

  • Corrosion proof
  • High sensitivity and accurate low-pressure control
  • Long service life
  • Integrated relief valve
  • Tamper proof by concealed adjusting screw

Low-pressure in-line regulators of this type are used as first stage regulators in a two stage system. Their temperature tolerance limits them to use with vapours only.
