Use
The lug-type wear-resistant check valve uses an alloy material with excellent wear resistance as the primary sealing material, and it also enhances the reliability of closing even under low pipeline medium pressure. This product is widely used in industries such as power generation, petroleum, chemical engineering, and metallurgy.

Working principle
The lug-type wear-resistant check valve is designed to prevent backflow of the medium in the pipeline. It allows the medium to flow only in one direction. Under the pressure of the medium flowing in one direction, the spring force acting on the valve disc is overcome, and the valve disc opens. When the fluid flows in the reverse direction, the medium pressure and the spring force acting on the valve disc...
Under the combined action, the valve disc closes, thereby shutting off the flow.
