Air-Operated Sequential Vapor ValveHandle fuel vapors safely and efficiently with this lightweight aluminum vapor valve. The air-operated valve allows fast vapor flow during loading and unloading. The poppet is designed to open into the tank, preventing accidental leakage from product surges or from a tank truck rollover. Easy-to-use air line connections are located outside the compartment for convenient installation and maintenance. The 3.5-inch vapor valve comes with male NPT threads or a TTMA flange for installation in conventional 16- or 20-inch manholes. Also available as an option is a Betts Vapor Vent Replacement Kit Hood Adapter to make replacing an existing Betts unit with an EBW unit as simple as possible. |
