The function of pressure reducing valves (pressure regulating valves) is, to reduce a varying or constant upstream pressure (inlet pressure) of the media to a constant reduced pressure (outlet pressure, back pressure) which is depending of the upstream pressure.

The pressure reduction occurs by throttling the free cross section between the seat and the cone. Any change in pressure on the downstream pressure side is immediately converted into a lifting movement of the valve cone.

At zero consumption, that is, when the consumption on the downstream pressure side is zero, the valve doesn’t close tightly.

The pressure reducing valves are suitable for compressible media, e.g. compressed air, natural gas, nitrogen, as well as for incompressible media, e.g. water, oil, fuels, LPG (propane, butane) etc.

They are mainly used in industrial plants, plant engineering and process engineering.

Pressure reducing valves can be supplied with flanges, weld ends or threaded connections.
