Pressure reducing valves

Pressure regulators for laboratory and analysis

These regulators allow to manually adjust an outlet pressure (pressure reducer) or an inlet pressure (overflow) on a fluid (liquid or gas) compatible with the materials used.

  • Devices designed to regulate low pressures (< 35 bar) have a metal diaphragm. Sealing with respect to the outside is ensured by a metal-to-metal seal.
  • Devices for regulating high pressures (> 35 bar) have a piston. Sealing with respect to the outside is ensured by an elastomer or plastic seal.

Electro-pneumatic converters

Bellofram converters are electro-pneumatic devices that reduce their supply pressure to a precisely regulated output pressure, the level of which is directly proportional to the amplitude of an electrical control signal.
