A. Hock MSR- und Electronic Service GmbH Valve Division Series E2000NR Electrical linear Actuator with fail-safe function SPECIFICATION In case of power failure, the electric linear actuator runs spring driven into the respective fail-safe position (thrust rod either extended or retracted). In modulating duty, the end position seating is made via limit switches. Low height due to compact, integrated unit Reduced maintenance requirement due to the prely mechanical system without hydraulic fluid. No sensitivity of the system regarding temperature variations. Electric manual operation via OPEN / CLOSE buttons in the actuator Permanant spring conception for safe operation. Mounting rods for easy mounting onto the valve Universally usable actuator due to control via 3- pont-step controllers, analogue input signals 0 10 V, 0 (4) 20 ma or fieldbus systems. Features TÜV (German Technical Control Board) Test according to DIN EN 14597 as an actuator for water and steam with fail-safe function in heating facilities. Stallproof synchronous motors ensure highest positioning accuracy. Limit switches easily adjustable, for stroke limitation or as signal for intermediate positions. Mechanical stroke indication via anti-rotation bar. Easy supplement to actuator with optinal devices due to modular design.
