Description
Electric quarter-turn actuators are designed for remote and local control of shut-off valves. Widely used in gas, oil, metallurgical and food industries, housing and communal services, etc. with ambient temperature from -20°...+70°C.
The enclosure is equipped with a heater (7-10W 220V) and has the following degrees of protection: IP67, NEME 4 and 6, anti-corrosion coating. The installation dimensions comply with the international standard ISO05211 / DIN3337. The actuator is equipped with a squirrel cage asynchronous motor, auto-locking of the actuator position, mechanical handle, thermal protection, X Y Z 10g vibration protection (0,2-34 Hz, 30 minutes) and is designed for repeated-short-time operation S2. The actuator stroke is 90° with an adjustment range of ±10°. The actuator stroke is limited by limit switches. Cable connection 2 x M18. Power supply is 24 V DC voltage.
