- Easy Installation: Short overall length allows installation in horizontal or vertical pipelines without special pipe support
- Extended Service Life: Seat is fitted in the body to prevent contact with flow media
- Energy Efficient: Large orifice size minimizes head loss, reducing pump energy consumption
- Space Saving: Short face-to-face dimension fits easily between standard gasket and line flanges
Check valves are automatic shut-off valves commonly used for preventing backflow or drainage in pipe systems. Often applied on the discharge side of pumps, they prevent system drainage if pumps stop and protect against backflow that could damage pumps and other equipment.
