Electric Over Hydraulic Valve Block

Our electric over hydraulic valve block combines electrical control signals with hydraulic power output. The pilot stage uses a proportional solenoid, while the main stage is a precision spool valve.

With PID closed-loop control, the system provides stepless regulation of pressure or flow, enabling smooth and accurate performance without step changes.

This design is especially suitable for injection molding machines, hydraulic presses, and automated systems requiring continuous closed-loop adjustment.

A built-in linear position sensor provides real-time feedback of spool movement to the controller, ensuring high control accuracy and stability.

The dynamic response frequency reaches 40 Hz, making it suitable for high-speed industrial automation applications.

Compared with pure hydraulic or manual systems, this electric over hydraulic valve block offers significantly improved precision and integration capability for modern production lines.

Special attention must be paid to electromagnetic compatibility and coil temperature rise during operation.

The maximum allowable temperature rise is 60°C, ensuring safe and stable long-term operation.

This product has been successfully supplied to manufacturers such as Midea and Gree, where it is used in fully automated production lines operating 24/7 under high reliability requirements.

Each unit is strictly inspected before shipment by our quality control team to ensure consistent performance.
