General Description
The Float ball type AIR RELEASE & VACCUM BREAKER, model NK-AR17 SERIES, was designed, manufactured and tested for allowing atmospheric air through the valve to rapidly displace draining liquid in the pipeline and prevent internal negative pressure damaging the arrangements potentially.
The Float ball type AIR RELEASE & VACCUM BREAKER, model NK-AR17 SERIES, was designed, manufactured and tested for allowing atmospheric air through the valve to rapidly displace draining liquid in the pipeline and prevent internal negative pressure damaging the arrangements potentially.
To prevent damage, vapor must be allowed into or out of the pipeline & at specified vacuum condition. The volume rate of venting depends upon the pipe size, the pumping rates and the temperature. Refer to API Standard 2000 for the procedures to determine venting requirements.
A AIR RELEASE & VACCUM BREAKER must be carefully maintained by a qualified valve technician.
It should only be assembled under clean conditions, preferably in a service shop environment. Carefully read and understand this manual before installing or attempting to repair a valve. Corporation WIN offers repair services for all products manufactured by NEOTECHKOREA
