BrassCraft Safety+PLUS excess flow valves and connectors incorporate state-of-the-art technology with precision engineering, providing an advanced solution to homeowners that helps protect against gas related fires and explosions. In the event of a gas line rupture or disconnect, the Safety+PLUS valve automatically activates to restrict gas flow at the appliance. This immediate action helps avert the potential for a hazardous buildup of gas in the home. Gas flow is controlled at the appliance where the rupture occurred; the rest of the home’s system will continue to function. The valve will remain activated until the gas line is properly repaired. Once repaired, the Safety+PLUS valve automatically resets to restore normal gas flow to the appliance.
