摘要

A vapor vent control valve arrangement (l0) for a fluid tank (l2) is disclosed. The valve arrangement includes a solenoid operated valve (28) with a normally-open parallel switch assembly (l6) and a normally-closed switch (42) in an electrical circuit (ll) to activate the solenoid valve. An impact switch (70) may also be provided as a safety precaution in the series circuit. The valve assembly is spring-biased to provide an over-pressure check valve function and also includes a back-pressure relief valve (62).
