Pressure Reducing Valve
without auxiliary power, for liquids and gases
The task of pressure reducing valves (also referred to as pressure reducing valves, pressure-controlled regulator) is that is reduced at a fluctuating (variable) or constant admission pressure of the steam to a constant, dependent on the form pressure (negative pressure). The pressure is reduced by throttling the free cross section between the seat and the cone. Each pressure change is immediately converted into a stroke movement of the valve cone on the back pressure side. At zero consumption, that is, when the consumption on the low pressure side is zero, the valve does not close tightly.
The pressure reducing valves are suitable for compressible media, such as e.g. Compressed air, natural gas, nitrogen, as well as for incompressible media, such. Water, oil, fuels, LPG (propane, butane), etc. They are mainly used in industrial plants, plant engineering and process engineering. The pressure reducing valves can be supplied with flange, weld end or threaded connections.
