Product details

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. Its specific functions include: Directional Control—acting as a directional control and fluid distribution valve within the hydraulic system, it directs high-pressure fluid to specific locations to execute operations such as prop raising and lowering, conveyor pushing, and support advancing. Structural Design—featuring an integrated valve spool design, the spool can be pre-assembled and then inserted into or removed from the valve bore as a single unit; this simplifies assembly processes and facilitates underground maintenance. Additionally, the structural design increases internal fluid flow areas, thereby enhancing flow capacity, reducing return-flow resistance, and improving the overall operating efficiency of the hydraulic system.

Business Scope

The company is a professional enterprise mainly engaged in the production of hydraulic support pipeline fittings for coal mines, and the products mainly include: buckling joints, straight, tee, reducer straight, reducer tee, Y-type tee, T-type tee, F-type tee, tee, elbows, intermediate joints, plugs, U-shaped pins, unloading handles, liquid injection gun, spherical disconnecting valves, etc. The advanced equipment can make the product quality higher, the production efficiency higher, the production cost lower, and enhance the competitiveness of the market, so that the enterprise can get a larger economic benefit.

"To do a good job, we must first sharpen our tools" Advanced equipment can improve product quality, increase production efficiency, reduce production costs, enhance market competitiveness, so that the enterprise can obtain greater economic benefits. For this reason, the company has invested a lot of money to buy a large number of advanced production equipment at home and abroad, such as Taiwan sawing machine, German cold-drawing machine, green forging electric screw presses, CNC machining centers, domestic advanced CNC machine tools and other equipment.
