Type "AR" Full Port Bronze Solenoid Valve - Normally Open
MAX. FLUID TEMP. 212°F
MAX. STATIC PRESSURE 300 PSI
Except valves listed for 500 PSI
TYPE "AR" FULL PORT
NORMALLY OPEN - 1/2" TO 3" PIPE SIZE
NO DIFFERENTIAL PRESSURE REQUIRED TO OPEN OPERATION:
Valve closes when energized and opens when de-energized. When the coil is energized the plunger presses the poppet, closing the pilot orifice, and opens a bleed passageway to permit pressure to build above the piston and seat it. Upon de-energizing the coil, the pilot orifice is opened, relieving the pressure above the piston allowing it to leave its seat. The bottom spring allows the valve to operate at zero pressure drop.
