Details

Product Overview: This series features a cushioned damping cylinder device that slows down the closing process, allowing localized backflow to gradually release into the system. This significantly reduces the water hammer force generated during pump shutdown, effectively eliminating the occurrence of destructive surge peaks. The shut-off seal is made from nitrile rubber, offering excellent sealing performance, superior shock absorption and wear resistance, extended service life, and easy maintenance.
