Solenoid proportional pilot pressure reducing valve – Direct operated type PRDP1M6 Hydraulic symbols Overview It consists of the DC proportional solenoid and spool type direct operated pressure reducing valve, and the position of the directional flow regulating valve and allows tilting angle of the variable capacity pump to be remotely controlled at a rate in proportion to the input current. Type indication Features 1. Special damping mechanism with a spring realises superior stability even at high pressure of 30.9 MPa (315 kgf/cm 2 ) being applied to the primary side. 2. During the initial adjustment or malfunction in the electrical system, manual operation can be done with the manual pressure adjustment thread.
