The DG4V30CMP7H7P1252 is a valve produced by Vickers for the DG4 Directional Valves series and is used to control hydraulic flow in automated machinery. Its spring centered, open center spool connects all ports at rest so flow is returned to tank until electrical command is given. The assembly withstands 350 bar (5000 psi) on the P, A, and B ports, while the T port is limited to 210 bar (3000 psi) to protect return lines. A maximum flow rate of 40 l/min (10.5 USgpm) defines the volume it can pass without excessive pressure loss. The solenoid requires 24 V DC at 30 W, and continuous energization is allowed by a 100 % duty cycle. Class F encapsulation shields the coil from vibration, and Class H insulation raises thermal endurance for reliable service under high ambient temperatures.
Hydraulic media supplied to the valve must meet ISO 19/17/14 cleanliness so the spool lands do not stick during rapid cycling. Installation follows the ISO 4401-AB-03-4-A subplate interface, and the CETOP 3 (NFPA D03) mounting pattern aligns the pressure and tank ports with standard manifold blocks used throughout industrial equipment. Fastening is completed with M5-0.8-6H bolts, which seat the body against the port face and resist loosening during pressure pulsations. When voltage is applied the spool shifts in 60 ms, providing prompt directional change to start actuator movement, and it returns to center in 40 ms once the coil is de-energized to stop flow quickly. These response times synchronize hydraulic motion with electronic commands while the standardized mounting features minimize service downtime in continuous-duty circuits.
