Flanged Vertical Check Valve

The vertical check valve is designed for vertical installation, with a disc that opens and closes along a vertical axis, making it suitable for applications where the medium flows from bottom to top. The disc features a short lift stroke and rapid response speed, enabling it to quickly prevent backflow of the medium.
