Product Overview


Single opening exhaust valve is mainly made up of body, bonnet, valve stem, floating ball, nozzle and other components. It was used for small diameter pipelines(pipes for DN50-200mm), it plays a role as a exhaust pipe in pipelines will not have suffocation or air resistance. For example, there will be negative pressure inside the pipes at any time when pumps come across power outage and automatic suction can protect the safety of pipelines.


Product Usage
