Proven lifesavers, breakaway valves separate when pull-strain loads on fluid lines exceed a predetermined value. Breakaway valves prevent fueling station drive-aways from becoming major disasters by uncoupling at a predetermined pullstrain and instantly sealing at both ends of the break. They can prevent costly damage to dispensers, eliminate station downtime and avert the major danger of runaway fuel spillage.

Breakaway valves can be reconnected in minutes by simply replacing the metal-tipped shear screw. Breakaway force provides ample protection for dispensers, while also preventing accidental disconnection caused by aggressive hose handling.

The primary function of breakaway valves is to protect the attached fuel-system lines from damage due to excessive separation loads. Breakaway valves safely separate at the fuse area, preventing a fuel-line rupture while sealing the fuel lines before the attached plumbing material can be stressed to the point of failure or leakage.

The breakaway fuse is usually designed to separate at 25% to 50% of the attached plumbing’s normal strength, allowing controlled and safe separation in the line, and valve closure before damage occurs.
