V3068A/B Hydraulic Solenoid Valve Block

The V3068A/B is a compact hydraulic solenoid valve block designed for reliable flow control. In the de-energized state, flow from port 2 to port 1 is closed while reverse flow is permitted through the check function. When energized, the 2-to-1 flow path opens. Multiple coil voltages are available for different hydraulic applications.

Overview

The V3068A/B hydraulic solenoid valve is a compact, direct-acting valve designed for controlling oil flow in hydraulic systems.

Its normally closed, two-way, two-position construction provides fast response, stable operation and reliable hydraulic control. The compact valve body saves installation space and is suitable for industrial machinery, mobile equipment and hydraulic power units.

The valve supports multiple AC and DC coil voltages and provides a maximum flow rate of 50 L/min at a maximum working pressure of 250 bar.

Operating Principle

When the solenoid is de-energized, ports 1 and 2 are closed to block hydraulic flow.

When the solenoid is energized, the valve opens the flow path from port 2 to port 1, allowing oil to flow in one direction.

Installation and Maintenance Notes

Use oil filtration of 20 μm or better to protect the valve and extend its service life
Use clean, contaminant-free mineral-based hydraulic oil
Use the specified solenoid coil voltage
Incorrect voltage may damage the solenoid coil
Confirm the oil inlet and outlet directions before installation
Do not exceed the maximum working pressure
Ensure the operating voltage is at least 85% of the rated voltage
