The multi-circuit directional control valve can split the flow into two or more independent hydraulic circuits, enabling the simultaneous operation of multiple pieces of hydraulic equipment.
Equipped with a built-in forced-air cooling system, it rapidly dissipates heat from the hydraulic fluid during continuous high-pressure operation, preventing issues such as excessive oil temperatures, pressure drop-off, and seal degradation or failure during prolonged use.

Tell us what you need. Available model and stroke combinations will be confirmed in the quotation.
High-capacity oil reservoir: An integrated orange tank with a capacity far exceeding that of standard tensioning pumps, ensuring sufficient fluid reserves for extended operations;
High-power drive motor: A vertical, high-power motor mounted on top, delivering higher flow rates and maximum pressure limits for rapid pressure buildup;
Multi-circuit solenoid directional valve assembly: An integrated valve block on top that splits the flow into multiple independent circuits, allowing simultaneous connection to multiple jacks or hydraulic tools and individual control of each circuit’s extension and retraction;
Front-mounted air-cooled radiator: A cooling fan on the front of the unit provides forced-convection cooling for the hydraulic fluid, preventing rapid temperature spikes during continuous high-pressure operation;
High-pressure piping and pressure gauge ports: Features internal high-pressure lines and dedicated mounting ports for pressure gauges to monitor the pressure of each circuit in real-time.
The multi-bank directional valve splits the flow into two or more independent circuits, enabling the simultaneous operation (tensioning or lifting) of multiple jacks—ideal for balanced multi-point lifting of bridge girders or parallel tensioning of multiple steel strand bundles;
Each circuit allows for independent directional switching and pressure regulation, offering the flexibility to perform either synchronized actions or separate, independent operations.
Equipped with a forced-air cooling system that rapidly dissipates heat during sustained high-pressure work, preventing issues common to standard pumps—such as excessive oil temperatures, pressure drop-off, and seal degradation—making it suitable for large-scale projects like expansive parking structures or multi-span bridge tensioning;
Higher motor power and pump displacement result in faster jack cylinder extension and retraction, significantly shortening the tensioning cycle per strand and boosting overall efficiency for large-scale projects;
Excellent pressure stability ensures smooth pressure buildup even at high flow rates and minimal pressure fluctuation during holding phases, meeting the precision requirements for prestressed tensioning. 4. Operational Versatility
Suitable for heavy-duty applications such as prestressed tensioning, synchronized whole-bridge jacking, and multi-point press-fitting of heavy components;
Features a robust, integrated frame structure capable of withstanding frequent site relocations and harsh, humid outdoor operating environments;
Can be upgraded with pressure sensors and an electronic control system into an automated CNC tensioning pump station, enabling automatic recording of tensioning data.
