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.
