This valve is to be used on the release side of the filling hose. The multi-porting is reducing the need for additional connections which is saving space and reducing the risk for leaks.
The stem travel can be adjusted which directly effects the orifice. Hence the vent-down process can be optimized regarding noise emissions by adjusting the valve on side.
The outlet check valve which is located downstream towards the vent line (stack) is integrated as well.
Double porting on left hand side eliminates need for Tee fitting
Connection for rupture disk
Check valve integrated on outlet
Adjustable stem travel = adjustable orifice
High leak integrity and compact integrated design
Low wear because of optimal materials of construction
Weep holes on connections for maximum safety
