Valves / Pressure reducers

Direct-acting pressure reducing valve, with diaphragm compensation and without auxiliary power. Controls the outlet pressure even if there are oscillations in the inlet pressure.

The valve closes when the downstream pressure increases.

Suitable for gases (air, nitrogen,...), liquids and steam.

Pressure range from 0.02 to 8 barg with several different actuators. Membrane with intermediate reinforcement fabric.

The condensation tank is available and is necessary when the fluid is steam or for liquids with temperature above 125ºC, to protect the membrane from overheating.

The reducing valve is not a safety valve and, when necessary, an overpressure protection must be installed.
