Largest Overpressure Protection Breadth in the Industry High Capacity Relief - Large 2-1/2 NPT vent provides a signiﬁcant increase in relieving capacity and level of overpressure protection to the downstream system. Internal Relief - Minimizes downstream pressure buildup by relieving gas through the diaphragm assembly and out the 1 NPT vent to atmosphere in the event of an overpressure situation.
