Pressure reducing valve is an automatic control valve with an internal pressure sensing element that reduces the upstream line pressure to a set level downstream and maintains the reduced pressure, irrespective of changes in upstream pressure.
Operation Principle of Pressure Reducing Valve
The action of pressure-reducing valves always generates heat energy because of the throttling effect. This heat generation must be taken into account when considering their application. Where two separate pressures are continuously required in a circuit, a two-pump system may prove a better solution than one using pressure-reducing valves. This will depend upon the flow and pressures required.
