Anechoic Check Valve

Anechoic Check Valve
Anechoic check valve is suitable for water supply and drainage pipeline,whose valve disk adopts imported central axis to both end which can open and close agilely, and can be installed both horizontally or vertically.Its disc use spring, whose fast closing can eliminate water hammer effectively.the disc is also features in good sealing performance and without noise during closing. Anechoic check valve have advantages like small volume, light weight, small fluid resistance, anti-fatigue and long service life etc.
