Operation | Automatic Oil Shutoff Valves
OPERATION All electro-mechanical valves require a constant supply of electrical energy to their holding actuator solenoids. Once the solenoid is energized, the manual reset valve may be opened manually, or the automatic reset valve will automatically open. Interruption of electrical power causes an immediate "trip" of the valve to its normally-closed position. The swinging gate body has carefully machined sealing surfaces. Frequent use and cycling actually helps to keep the valve clean.
TEMPERATURE LIMITS All valves can handle fluid temperatures from –20°F (–28°C) to +250°F (+121°C). Ambient temperature limits vary. Any valve on this page us- ing dc voltage and all ½ " and ¾ " series 1517 Valves can handle ambient temperatures from –20°F (–28°C) to +125°F (+52°C). The other valves on this page handle ambient temperatures from –20°F (–28°C) to +140°F (+60°C).
