DOT and ASME Multivalves for Vapor Withdrawal 6532, 6533, 6542 and 6543 Series

These Multivalves® permit vapor withdrawal from ASME containers up to 50 sq. ft. surface area and DOT containers up to 420 lbs. propane capacity. They allow on-site cylinder filling without interrupting gas service.

Features 6542 and 6543

    • Incorporates high capacity filler valve with double back checks, service valve, fixed liquid level gauge, pressure relief valve and built-in baffle tube into one compact unit.
    • Higher filling capacity is combined with back check protection by placing the secondary back check at the bottom of the baffle tube, creating a larger flow area through the body.
    • Pre-drilled hole in 1¼” wrenching flat accepts a drive screw for attaching relief cap and chain.

Features 6532 and 6533

    • Similar but smaller than the 6542 and 6543, these are generally used for replacement on existing containers with ¾” NGT openings.
    • Secondary back check placed in the body of the valve to help minimize reverse flow in the event the upper back check shears off or requires replacement.
    • The MultiBonnet® option allows quick and easy repair of bonnet.
