Hydraulic Lever Valve Block

Our hydraulic lever valve block uses a mechanical lever combined with a hydraulic pilot linkage system. It is designed for applications requiring manual fine adjustment or mechanical remote control, especially in environments where electronic systems are unreliable.

The rated working pressure is up to 31.5 MPa. Nominal sizes range from 6 mm to 20 mm. Operating force of the lever is less than 50 N, making it easy to control.

The stroke adjustment range is 0–15 mm. The valve body is equipped with a precision-machined spool and return spring. The lever ratio amplifies input force, enabling smooth and linear control of oil flow.

This design eliminates dependence on electronic components, reducing failure risk in high-temperature, high-humidity, or high-dust environments. It is especially suitable for coal mines, steel mills, and other harsh working conditions.

Internal leakage is controlled within ≤2.5 mL/min. Response time is approximately 0.3 seconds, ensuring fast and stable operation.

Compared with electro-hydraulic valves, this hydraulic lever valve block operates purely through mechanical-hydraulic principles. While it offers lower cost and higher environmental reliability, it does not provide full automation control.

It is widely used as a backup control unit or manual override point in hydraulic systems.

We have supplied this product to multiple coal mining equipment manufacturers. In underground mining environments, where moisture, dust, and vibration are severe, solenoid valves often fail. Our lever valve block has demonstrated stable and reliable performance under these conditions.
