Product Information：
This Brass One Way Valve is mainly used for pipes where the medium or fluid flows in one direction. It can automatically prevent the fluid or medium from flowing back, and only allows the fluid or medium to flow in one direction.
Brass One Way Valve is the kind of brass check valve that can be installed horizontally and vertically. It is mostly used in building water supply and drainage, air conditioning, solar energy, boilers and other systems. It is easy to push the baffle open and flow through. When the baffle is reversed, the baffle is pressed on a step in the valve body to prevent the water from flowing back.

There are three commonly used check valves:
Spring type: the liquid is from bottom to top, relying on the pressure to push up the valve flap controlled by the spring. After the pressure disappears, the spring force pushes down the valve flap to seal the liquid back flow. Commonly used for check valves with a small diameter;
gravity type: similar to spring type, relying on the gravity of the valve disc to close to prevent backflow;
swing type: the liquid passes through the valve body directly, and the pressure is used to push the rotating disc on one side , After the pressure is lost, the valve flap returns to position by its own weight, and the reverse liquid pressure closes the valve flap.
