It is a 4/3-way (4 ports, 3 positions) directional control valve. Its primary function is to precisely control the flow direction to hydraulic actuators (like cylinders or motors) in industrial systems. The "C" spool with a closed center (all ports blocked in neutral) is designed to hold an actuator firmly in position when the valve is not energized.
The valve is rated for a maximum operating pressure of 315 bar and a nominal flow rate of 30 L/min (with a maximum of 60 L/min). It is crucial not to exceed these limits to ensure reliable operation and valve longevity.
The "C" designates the spool type. For this 4/3-way valve, a "C" spool has a closed center in the neutral (de-energized) position. This means all four ports (P-pressure, T-tank, A & B-work) are blocked, which locks the connected actuator in place, preventing it from drifting under load.
The valve requires a 24 VDC power supply, with a nominal current of 0.45A (10.8W). It features a DIN 43650 Form A electrical connector with an M12x1 cable entry. The coil has 100% duty cycle and IP65 protection.
For optimal performance and long service life (>20 million cycles), ensure:
- Fluid Cleanliness: Maintain fluid cleanliness to at least NAS 1638 Class 8, with a filtration rating of 25 μm nominal (10 μm absolute)
- Compatible Fluids: Use standard mineral-based or synthetic hydraulic oils within a viscosity range of 10 to 380 mm²/s
- Temperature: Operate within the specified ambient and fluid temperature range of -20 °C to +80°C
