Product details

The alternating check valve is primarily used to prevent the automatic unloading of the hydraulic support caused by a surge in pressure within the return line due to a malfunction. It ensures the smooth flow of return fluid from the support into the return line while blocking any backflow from the return line into the support, thereby meeting the operational requirements of the support's hydraulic components.
The characteristics of the alternating check valve include:

Unidirectional control: Fluid enters in only one direction; for instance, when fluid enters through port A, it pushes the valve core to the right, allowing flow only from A to C and preventing reverse flow.
Structural composition: It consists of components such as a connector, O-ring seal, valve core, valve seat, and valve body. The valve core and valve seat form a sealing interface that controls unidirectional flow and provides a sealing/locking function, ensuring the operational requirements of the hydraulic support components are met.

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.
