One-way valve, slso known as a check valve, a one-way valve switch, is a fluid control device that only allows fluid to pass in one direction. It usually consists of a movable valve disc and a valve seat. When the fluid exerts pressure from one side, the valve disc is pushed open and the fluid can pass smoothly. However, when fluid applies pressure from the other side, the disc is pushed back onto the seat, preventing reverse flow. The main function of the one-way valve is to prevent fluid from flowing back and avoid liquid or gas causing reverse flow or reverse pressure in the system. It is often used in areas such as piping systems, hydraulic systems, automotive engines and air conditioning systems. In general, the one-way valve has the advantages of being simple, reliable, and compact, and can control the direction of the fluid and prevent backflow. It plays an important role in various industrial and mechanical equipment, ensuring the normal operation and safety of the system.Material: Aluminum alloy, stainless steel
