New magnatrol valve 18A42 1/2" brass 120 vac n.c
NEW MAGNATROL VALVE 18A42 1/2" BRASS 120 VAC
Type A Full Port Bronze Solenoid Valve - Normally Closed - Internal Pilot Operated
Valve opens when energized and closes when de-energized. When the coil is energized the pilot valve opens, relieving the pressure above the piston, which is then lifted from its seat by the laminated plunger. Upon de-energizing the coil, a spring closes the pilot valve and opens a bleed passageway to permit pressure to build above the piston and seat it.
