Please consult factory for PN25 and antishock device whenever there is waterhammer issue.

. 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.
. With special fat body design to lower the sewage water flow speed, and let the air out but keep sewage water underneath.
. Keep dirty or corrosive liquid inside the body for safety during operation and no harm to human & surrounding environment
. Internal body guide and upper round wall keep float moving on its rail and keep liquid turbulence flow within this area.
. Much bigger air flow through the nozzle even for higher viscosity liquid.
. Outside screen will be an option for safety and prevent insects or birds in.
. Fully fusion epoxy coated inside and outside of valve body for long term services.
. Manufacturing standard meets BS EN 1074-4, AWWA C512. Flange drilling and dimension meets BS EN 1092 and ANSI flange.
