Victaulic® FireLock™ S014749C00 Auto Drain Assembly, Brass

The Victaulic® Series 749 auto drain is used in Series 756 dry and Series 758 actuated valves that have either a Series 753/753-A dry actuator or a normally closed solenoid valve. Once tripped, the auto drain constantly drains the piston charge line, preventing the piston from repressurizing. The auto drain remains open until it is manually reset during the valve resetting procedure.
