Check Valve With Single Disc

The single-disc check valve is also called a single plate check valve, a wafer check valve: it is a valve that can automatically prevent fluid from flowing back. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve flap is automatically closed under the action of the fluid pressure difference, gravity and other factors to prevent the fluid from flowing back. It can be installed horizontally or vertically. For vertical installation, pay attention to the flow of water from the bottom to the top, and pay attention to whether the installation direction is correct during installation.
