A Y-Type Grooved Check Valve is a specialized valve designed to prevent backflow in pipeline systems while allowing fluid to flow in one direction. It features a Y-shaped body that enhances flow efficiency and reduces pressure drop. The grooved end connections facilitate easy installation and maintenance, making it suitable for various applications. Typically made from durable materials like stainless steel or carbon steel, it can handle different media, including water, steam, and oil. This valve is commonly used in HVAC systems, fire protection systems, and industrial processes where backflow prevention is crucial

A CHECK VALVE IS a VALVE THAT ALLOWS FLUID TO FLOW IN a fixed direction and automatically PREVENTS it from FLOWING in THE opposite direction (backflow).- 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.
