Check valve refers to a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent medium backflow, also known as a check valve, one-way valve, or backflow valve. A check valve is an automatic valve that primarily functions to prevent media backflow, prevent pump and drive motor reversal, and dis1
Overview of piston type quick opening mud discharge valve: The J744X hydraulic piston type quick open sludge valve and pneumatic piston type quick open sludge valve are generally installed outside the bottom wall of various water treatment plants or industrial sedimentation tanks to remove sediment and dirt from the sedimentation tank.
The telescopic butterfly valve has the function of automatically compensating for the thermal expansion and contraction of pipelines for easy loading and unloading. It is the best device for regulating flow and breaking fluid on industrial pipelines such as petroleum, chemical, power, papermaking, water supply and drainage, and municipal constructi1
Product Overview: The upper mounted bi-directional sealed eccentric hemispherical valve has been successfully developed by absorbing and digesting advanced technology from both domestic and international sources.The new product is to fix the metal ball crown on an eccentric ball.

The valve stem of WZ41H corrugated pipe gate valve adopts a double sealing structure of corrugated pipe and packing, ensuring no leakage sealing at the valve stem, especially suitable for pipelines with flammable, explosive, toxic and valuable media. The sealing structure of corrugated pipes is designed reasonably, resistant to fatigue, and has a l1
Electric flange ball valve has the same 90 degree lifting action, with a circular through-hole or channel passing through its axis. The ratio between the sphere and the channel should be such that when the sphere rotates 90 degrees, it should all appear spherical at the inlet and outlet, thereby cutting off the flow.
The PZ673H pneumatic knife gate valve is a complex automation control instrument composed of various pneumatic components and valve bodies. Commonly used in situations that require quick cutting or opening. Dual function: Two position control for valve opening and closing; Single action: (Spring reset): In the event of electrical and pneumatic circ1
The difference between a single clip LT type center line butterfly valve and a double clip center line butterfly valve is that the flange around the valve body has threaded holes. This product can be used for clamp connections between pipelines, as well as for connections between pipeline ends, for emptying pipeline media. This product has good val1
