The function of steam pressure REDUCING VALVE is accomplished when pressure sensor, pressure controller and steam pressure reducing valve work combine, making a gravity of action in mechanical coherence. The opening of the valve is determined by two techniques: the drawing out of spring by working on screw for adjustment. The second way is the opening of the steam pressure reducing valve by the power of steam. The former way is called pilot-method of steam pressure reducing valve while the latter is called direct method.

Hydraulic component work when potential energy of pushed-in fluid is converted into physical power of mechanical muscle. The pump keeps on pushing the fluid into the main valve and from onward, hydraulic pressure reducing valve is installed at various places to control and maintain the pressure. In hydraulic component, hydraulic pressure reducing valve is a functional tool, not merely safety valve for relief but it activates the force of the machine by leveling the pressure. In a hydraulic unit, hydraulic pressure reducing valve can perform various function and hydraulic pressure reducing valve can be cartridge style or pipe union sort. Without hydraulic pressure REDUCING VALVE, the unit can
