Electric Spring Return Actuator - Failsafe, Weatherproof, Corrosion Resistant

Quick Overview

• Fig no: NE-SR5
• 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 1, 2, 3, 3R, 4, 4X, 5 and 12. The NE-SR5 actuator is available with three cycle times -- 10, 15 and 30 seconds; as well as two voltages -- 115 VAC and 220 VAC. Please refer to NIBCO technical data sheets, valve selection guides and catalog for engineering and installation information.
