Frequently Asked Questions

What is the working principle of a multi-way valve?

The working valve plates are generally grouped in configuration. The inlet valve block has a built-in tee bypass pressure compensation function with an overflow valve and relief valve acting as logic components. This allows precise control of fluid direction and pressure in complex hydraulic circuits.

How do I select the right electromagnetic valve?

Selection is based on four key factors: applicability (fluid compatibility), stability (consistent performance), safety (fail-safe operation), and economy (cost efficiency). The fluid in the pipeline must match the valve's rated media type.

Can I add remote control to my crane system?

Yes. Adding remote control to truck lifting equipment significantly improves efficiency, safety, and energy savings. Our SD series pilot and pneumatic control valves are ideal for retrofitting existing cranes with wireless operation.

What industries use your hydraulic valves?

Our products are widely applied in agriculture, construction, petroleum, fishery, mining, material handling, and industrial automation systems requiring reliable hydraulic control.
