PNEUMATIC VACUUM BREAKER HXQP DN40-600
1 SME vacuum breaker is designed to prevent vacuum conditions from occurring in pipes or tanks.
2 It is mounted at critical pipeline high points and allows for rapid inflow of atmospheric air to reduce vacuum conditions in piping systems.
3 SME vacuum breaker series are designed and produced in compliance with manufacturer’s standard, within framework of standard JB/T8691-1998, test and inspection per GB/T13927-2005.
4 SME vacuum breaker is a safety valve. During critical vacuum conditions caused by power failure or rapid draining of the piping system, the pressure difference between the inside vacuum and outside air will cause a downward force on the valve disc.
