Belimo Actuator Open/Close 24VAC/DC 90Nm IP67 Terminals 35s F07 DRC24G-T-7

This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 90 Nm and can open/close the valve in 35 seconds. This actuator requires a supply voltage of 24 V AC/DC and has a visual positioning indicator to clearly see the valve position. The actuator features two-point (open-close) control. The actuator mounts to a quarter turn valve with an ISO 5211 F07 flanges. The actuator has a durable plastic housing and has an IP67 protection rating. This actuator can operate within ambient temperatures between -30 and 50 °C (-22 and 122 °F). A power cable can be easily attached via the terminal block.

The actuator is equipped with overload protection, the actuator doesn't need limit switches and will stop automatically when the end stop is reached. Due to its non-linear torque characteristic, the actuator is only suitable for butterfly valves and not for other valves. Manual override is possible using a push-button, which disengages the gear train as long as the button is pressed or remains locked. The actuator can be directly mounted on the butterfly valve. The mounting orientation relative to the butterfly valve can be chosen in increments of 90°. The actuator is suitable for outdoor use and is protected against UV radiation, rain/snow, dirt/dust, air humidity, and frequent significant temperature fluctuations. To prevent internal condensation, it's recommended to use the actuator with separately orderable, factory-installed heating. The housing cover must be removed for manual override.

Pros:

• The ISO 5211 F07 mounting flange fits many quarter-turn valves
• Manual override
• The actuator is overload protected
• Visual position indicator
• The actuator is suitable for outdoor use

Cons:

• Can only be used for butterfly valves
• The time to open/close of 35 s is slow for some applications
