PRECISION REGULATOR - SINGLE STAGE - FOUR PORT VERSION

LINE REGULATOR FOR USE IN PURE GAS SUPPLY SYSTEMS

This single-stage line pressure regulator is used in gas supply systems for pure, inert, flammable, oxidising gases and gas mixtures up to gas purity 6.0. It is not usable for corrosive and/or toxic gases and their mixtures.

SPECIAL FEATURES:

  • Low outlet pressure
  • Very fine adjustment
  • The large housing diameter of this pressure reducer allows large metal diaphragms and thus very fine adjustment of the back pressure at comparatively high flows down to 250 mbar
  • The line pressure regulator reduces the line pressure with very small hysteresis to very low supply pressures
