NIBCO, T117028, NE-SR5 Series Electric Spring Return Actuator, Failsafe, Weatherproof, Corrosion Resistant
The 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.
