The function of pressure reducing valves (pressure regulating valves) is, to reduce a varying or constant upstream pressure (inlet pressure) of the steam 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.
There is no need for additional accessories such as a water seal pot. It is possible to install the valve quick and easy.
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.

The pressure reducing valve T65 is 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.
The function of pressure regulating valves (pressure reducing 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 independent of the upstream pressure.
The pressure reduction occurs by throttling the free cross section between the seat and cone. Via a pulse line, which is already installed on the valve, the reduced pressure presses on a control piston. As a result, any change in pressure on the downstream pressure side is immediately converted into a lifting movement of the valve cone.
The valve is well suited for intermittent consumption. At zero consumption, that is, when the consumption on the downstream pressure side is zero, the valve closes safely by low pressure increase.
The pressure reducing valve T679 is suitable for compressible media, e.g. steam, compressed air, natural gas, nitrogen, as well as for incompressible media, e.g. water, oil, fuels, LPG (propane, butane) etc.

The pressure reducing valve T95 is 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.

The function of overflow valves (relief valves, pressure retaining valves) is, that the outflow of the medium at a set pressure, in which an existing back pressure or vacuum having no effect on the set over pressure (retaining pressure). The above listed items are characteristic for an upstream pressure regulator, by comparison to a normal safety valve. The safety valve is only a device to prevent a specific pressure from being exceeded (set pressure).
The overflow valve T27 is a single-seat valve and is especially suitable for incompressible media, for example water, oil (lubrication oil, fuel oil, HFO, LFO, MGO), etc. The valves are fully relieved so that the back pressure has no effect on the set (overflow) pressure, only the flow quantity changes according to the pressure difference.
They are mainly used in pump circuits to keep a certain pressure constant.
The sealing between the guide sleeve and the cone takes place with an O-ring.
The overflow valves can be supplied with flanged or threaded connections.
They are available in straight and angle form.
