Technical Data:

Size range:DN 25-300MM
Pressure ratings:1.0Mpa, 1.6Mpa(Thread)
1.0Mpa,1.6Mp,2.5 Mpa(Flange)
Working temperature: -10°-80°C.
Flow media: clean water

 

Features:

. Advanced design with simple mechanism, strong float to prevent cracking during sudden water hammer& quick closure.
. Aerokinetic 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 fl oat.
. 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 stanless steel screen will be an option for safety and prevent insects or birds in.
. Fully epoxy coated inside and outside for long term services.
. Manufacturing standard meets BS EN1074-4, AWWA C512
. Flange drilling and dimension meets BS EN 1092 and BS EN 558 and ANSI flange.
 
Service Fields:

For water system, fire fighting, irrigation system.
