PRODUCTS CENTER
The control valve assembly is primarily used to manage the lifting, advancing, and side-shield operations of hydraulic supports. It serves as a critical component in the control systems of fully mechanized coal mining face supports, fulfilling the dual mission of ensuring worker safety and enhancing production efficiency.
The company is a professional enterprise mainly producing coal mine hydraulic support pipeline fittings. Its products mainly include: buckling joint, straight-through, tee, reducing straight-through, reducing tee, Y-shaped tee, T-shaped tee, F-shaped tee, four-way, elbow, intermediate joint, plug, U-shaped pin, unloading handle, liquid injection gun, spherical stop valve, etc.
The safety valve prevents overloading of the hydraulic prop or jack, ensuring the support's yieldability and constant resistance. When the roof pressure exceeds the support's working resistance, the valve releases hydraulic pressure from the prop's working chamber; this not only maintains a constant working pressure but also provides overload protection.
