CHECK VALVE
The check valve refers to a valve that automatically opens and closes the valve flap by means of the flow of the medium itself, and is used to prevent the back flow of the medium, which is also called a check valve, a check valve, a reverse flow valve, and a back pressure valve. The check valve is an automatic valve whose main function is to prevent back flow of the medium, prevent the pump and drive motor from reversing, and discharge the container medium.
According to the structure, check valve can be divided into three types:
1. Lift Check Valve: Lift check valves are available in both vertical and straight versions.
2. Swing Check Valve: The swing check valve is divided into three types: single-lobed, double-lobed, and multi-lobed.
3. Butterfly Check Valve: The butterfly check valve is divided into a butterfly double flap and a butterfly single flap.
The above several check valves can be divided into four types: a screw connection, a flange connection, a welding and a clip type connection.Yuzheng Valve Co.,Ltd is a professional Check Valve Manufacturer China, we provide you with a variety of valves.

H12W Stainless Steel Vertical Lift Check Valves are designed for efficient fluid control in various industrial applications. Crafted from high-quality stainless steel, these valves offer durability and resistance to corrosion, ensuring long-lasting performance. Their vertical lift mechanism provides reliable operation, preventing backflow and ensuring unidirectional flow of fluids. Ideal for use in water treatment, chemical processing, and other demanding environments, these valves are engineered to meet the highest standards of safety and reliability.
The CLIP DISC TYPE CHECK VALVE IS A single disc SWING ON THE CLIP connection CHECK valve, in the pipeline as a device to prevent medium counterflow, they are ultra-thin CHECK valve, H74X, H74H TYPE CLIP DISC type CHECK valve has the advantages of simple structure, beautiful appearance, light weight, easy installation and so on- Wenzhou Yuzheng Valve Co.,Ltd
1. Check valve refers to a valve whose opening and closing part is a round disc and acts to block the backflow of media by its own weight and medium pressure. It is an automatic valve, also known as check valve, check valve, return valve or isolation valve. The motion mode of valve disc is divided into lifting type and swing type. Lift check valves are similar in construction to globe valves, except that they lack a stem that drives the disc. 2, the medium from the inlet end (lower side) into, from the outlet end (upper side) out. The valve is opened when the inlet pressure is greater than the sum of disc weight and flow resistance. On the contrary, the valve is closed when the medium flows back. 3. Swing check valves have an oblique disc that rotates about the shaft and work in a similar way to lift check valves. The check valve is often used as the bottom valve of the pumping device to prevent the return of water. The combination of the stop valve and the stop valve can play the role of safety isolation. The disadvantage is that the resistance is large and the sealing is poor when closed.
High platform ball valve and flange gate valve is the same type of valve, the difference is that its closing part is a ball, the ball rotates around the center line of the body to achieve the opening and closing of a valve. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. - Wenzhou Yuzheng Valve Co.,Ltd
