Product Description
Features
Advanced design with simple mechanism, strong float to prevent cracking during sudden water hammer and quick closure.
Self-moving mechanism to resist blow shut under higher air velocity even up to sonic velocity of air.
No arms or levers to prevent vibrating, bending, direct closure of the float.
Smooth cage outside of the float, keep float moving in specified guide rail.
Bottom rubber buffer for collision prevention, and drain easy with proper holes around the cage during vacuum.
Outside screen will be an option for safety and prevent insects and birds in.
Fully fusion epoxy coated inside and outside of valve for long service life.
Good for distribution pipeline system, if for transmission pipeline with high impact water hammer, the anti shock device should be required.
