NE-SR5 Series Electric Spring Return Actuator, Failsafe

NIBCO, T117028, NE-SR5 Series Electric Spring Return Actuator, Failsafe, Weatherproof, Corrosion ResistantThe NIBCO Series NE-SR5 line of electric spring return actuators is designed for use in environments where automatic closing/opening is required upon loss of power. When power is available the device operates like a normal quarter-turn actuator. Under powered operation, the spring pack travels with the movement of the actuator. Under powered stopped conditions, the actuator and spring are held in position via the electric mechanical brake. Under loss of power, the spring is released and drives the actuator to the pre-designated failsafe position. The actuators include a thermostat and heater. The series also features an electric mechanical brake. The enclosures are certified to NEMA Type 4. The NE-SR5 actuator with cycle times 10 second; as well as voltage - 115 VAC.Engineered with a modular approach, NIBCO electric and pneumatic actuation systems offer the flexibility to actuate new valves or to retrofit existing valves with unprecedented ease. Both electric and pneumatic actuation systems feature an ISO standard mounting design, assuring long-term industry acceptance.Features:Heater and thermostat installedPermanently lubricated steel gear trainHardened steel female drive couplingElectric mechanical brakeOperating temperatures -40°F to +140°FThermally protected, capacitor run, single phase motorClockwise (CW) spring returnTwo 1/2" NPT conduit entrancesCaptive hex bolts on enclosureAdjustable mechanical stop at the failsafe location115 voltageTorque 300 to 700 in/lbF04 and F05 DIN/ISO mount and driveEnclosure certified to NEMA type 4.
