THREADED VAPOR
CHECK VALVE
Use this vapor check valve to return vapor to the truck during
terminal loading and service station drops. The 3" poppet opens
when coupled and closes when disconnected, preventing the
vapors from escaping into the atmosphere. The valve has 3" or
4" female NPSM threads, a 4" cam and groove, and tapped
mounting holes for the EBW® air interlock brake. The 303 Series
is available without a poppet to serve as a male quick coupler
with an air interlock valve mounting pad.
