Pre-Pressure compensation multiple valves

  • Specifications
  • Performance
  • Application

? The first section is electro-hydraulic proportional control.

? The overall structure with cast oil passages. 

? Two parallel oil passages. 

? The function of dual pump supply and flow distribution can be achieved as needed. 

The main relief valve is connected in a cartridge style.

The directional valve operates on the principle of load sensing and provides excellent speed control performance. 

The system is equipped with a pressure compensator, and the flow to the actuator is controlled only by the opening of the directional valve, unaffected by changes in load pressure.

Multiple medium and small load actuators can work simultaneously without interfering with each other. 

The main relief valve has a remote control port, and the working ports have secondary relief valves. The secondary relief valves at the oil ports of the two sections supplied by Pump 2 have low-pressure replenishing functions to prevent cavitation. 

Suitable for various engineering machinery, mobile cranes, truck-mounted cranes, large or telescopic forklifts, drilling rigs, municipal machinery, forestry machinery, and fixed equipment.
