Model T7 steam
Pressure reducing valve – Model T7
self-operated, for steam
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 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. 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.
