Overview

The valve is featured by original structure, reasonable design,small profile, lightweight, outstanding sealing performance, strong circutating capability, little flow resistance, slow shut, noise elimina-tion, no vibration and noise. Functioned to effect optimal time for slow shut and for eliminating water hammer according to different occasions, triis valve is mainly used in water supply and drainage pipeline in highrises and fire control system, and mounted at the out-led of pump to cut off backflow of medium, eliminate destructive wa-ter hammer, ensure the safe operation of pipeline and pump, and ac-tualize distinguished energy-saving effect.
