Multifunction Valve

Patent Number: ZL200920026192.8

The multifunction valve is the heart for the single hydraulic prop. It has the three functions of injecting liquid to lift the prop, safe overflow, and unloading to return the prop. Hence, it is called three-use valve. Its quality directly affects the normal use of the single hydraulic prop, so it is hailed by workers as life valve.

The operating characteristic of this device is constant resistance. Using this product in the hydraulic prop brings great benefit for managing roof, reducing roof collapse, and reducing periodical peak pressure.

Our company started producing multifunction valve in 1982. With stable quality, our product has won the title of "High Quality Product in Shandong Province". Currently, our annual production capacity reaches 500,000 pieces. The raw materials have gone through intermediate frequency quenching and tempering, thus ensuring the strength of the product. All parts are processed on the production line composed of numerically controlled lathes, which effectively guarantees the quality of the finished products. The surface anti-corrosion treatment has been changed from the original tinning to the current multi-element alloy deposition and electrophoretic paint process, so as to adapt to the application and promotion of eco-friendly single hydraulic prop. In addition, we have various test equipment.

We currently provide more than 20 types of multifunction valve, including standard type, anti-splashing type, lengthened type, large flow type, medium flow type, centralized control type, hydraulic control type, and so on, meeting different market needs.
