The Single Disc Piston Check Valve is an essential component designed to automatically prevent fluid backflow. This valve operates by opening its disc under the action of fluid pressure, allowing fluid to flow smoothly from the inlet side to the outlet side. When the pressure on the inlet side drops below that of the outlet side, the disc closes automatically, influenced by fluid pressure, gravity, and other factors, effectively preventing fluid backflow. This versatile valve can be installed in either a horizontal or vertical orientation. For vertical installations, it is crucial to ensure that the fluid flows from the bottom to the top. Proper attention to the installation direction is necessary to guarantee the valve functions correctly and efficiently.
