Brief introduction:

    The Komatsu excavator PC120 cartridge type hydraulic pressure reducing valve by adjusting the inlet pressure reducing to a desired outlet pressure by adjusting the inlet pressure, rely on the inner spool and spring, automatically stable outlet pressure. The pressure reducing valve is a partial resistance of the throttling element can be changeable, i.e. by changing the throttle area, so that the flow velocity and the kinetic energy of the fluid changes accordingly, resulting in different pressure loss, so as to achieve the purpose of decompression. And then rely on the adjustment of the control and regulating systems, so that the pressure fluctuation and the spring force of the valve is keeping equilibrium, the pipes at the outlet port of valve is kept constant pressure within a certain error range.

    There are two types of pressure reducing valve, direct operated and pilot operate:

    The Direct operated pressure reducing valve rely on the balancing effect of the spool and overflow aperture of the overflow role regulator by inlet throttling effect of reduced pressure, adjusting spring can be changed within a certain range so that the output pressure .

    The Pilot operated pressure reducing valve works works with direct-acting outside the main valve body and a small direct operated pressure reducing valve, the main valve is controlled by it . Pilot operated pressure reducing valve regulator oil supplied by small direct acting pressure reducing valve. Small direct operated pressure reducing valve mounted inside the valve body, known as the internal pilot operated type valve; the small direct operated pressure reducing valve mounted on the outside of the main valve body, called external operated type valve.
