ZHF-V series of Vapor Check Valve Adaptor
AILE'S ZHF-V vapor check valve adaptors are used on the vapor recovery riser pipes on an underground storage tank. Dual point vapor recovery systems provide an easy and economical installation at new locations and faster drop times than coaxial systems due to a straight 4" drop across the top and vapors collected from 3" or 4" riser pipe. The vapor check valve adaptor permits coupling to the vapor return line from the underground tank in dual point systems. The poppet design seals off the vapor path when not coupled.
Constructed of anodized aluminum body.
Eliminates digging---Slips into existing drop tubes.
Fits all 4" vapor recovery elbows.
