It is a 4/3-way directional control valve with an "E" spool configuration. The primary function is to control hydraulic actuators. The "E" spool features an open center: in the neutral (de-energized) position, the pressure port (P) is connected directly to the tank port (T), while both work ports (A & B) are blocked. This design allows the hydraulic pump to unload to tank with minimal pressure drop when the valve is in neutral, reducing energy consumption and heat generation.
Pressure: Maximum operating pressure of 315 bar.
Flow: Nominal flow rate of 30 L/min (maximum 60 L/min).
Voltage: 24 VDC power supply (0.45A nominal, 10.8W).
Filtration: Requires fluid filtration of 25 μm nominal (10 μm absolute) and cleanliness of NAS 1638 Class 8 or better.
Temperature: Operating range of -20 °C to +80°C for both ambient and fluid.
The open center configuration (P connected to T in neutral) is highly energy-efficient. It allows the hydraulic pump to circulate fluid back to the tank with very low backpressure when no actuator movement is required. This significantly reduces power consumption, minimizes heat buildup in the hydraulic system, and extends component life, making it ideal for mobile equipment and systems with long idle periods.
This valve is particularly well-suited for: Mobile hydraulic systems (tractors, loaders, excavators) where energy efficiency is critical; Material handling equipment that frequently idles; Systems requiring pump unloading to reduce wear and save energy; Any application where minimizing heat generation during standby is a priority.
