GRC24G-5 Rotary Actuator, 40 Nm, AC/DC 24 V, 35 s
- Rotary actuator IP66
- Torque 40 Nm
- AC/DC 24 V, open-close
- Running time 35 s / 90°
- Manual override temporary, permanent
- Connection cable (FRNC) length = 1 m
Fields of application: The actuator is particularly suitable for utilisation in outdoor applications and is protected against the following weather conditions: - UV radiation - rain / snow - dirt / dust - Humidity - Changing atmosphere / frequent and severe temperature fluctuations (recommendation: use the actuator with integrated factory-installed heating which can be ordered separately to prevent internal condensation)
Simple direct mounting: Simple direct mounting on the rotary valve or butterfly valve with mounting flange. The mounting orientation in relation to the fitting can be selected in 90° steps.
Manual override: Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked). The housing cover must be removed for manual override.
High functional reliability: The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.
Adjustable angle of rotation: Adjustable angle of rotation with mechanical end stops. Standard setting 0 ... 90°. The housing cover must be removed to set the angle of rotation
Combination valve/actuator: For valves with the following mechanical specifications in accordance with ISO 5211 F05: - Square stem head SW = 14 mm for form fit coupling of the rotary actuator. - Hole circle d = 50 mm
