Schneider Electric MS40-7043 Damper/Valve Actuator

The Schneider Electric MS40-7043 Damper/Valve Actuator delivers precise modulation for dampers and globe valves. This electric actuator is designed for modulating, proportional control with a spring-return operation, offering reliable fail-safe performance in HVAC applications.

Powered by 24 Volt AC and 22–30 Volt DC, with a control signal range of 2 to 10 VDC or 4–20 mA, it supports flexible integration into building automation systems. The unit provides 35 in-lb torque, 95° rotation, and a compact 3 ft plenum cable with a 1/2 in conduit connector.

Built for durability, the MS40-7043 features a NEMA 2 enclosure, a 5/8 in shaft, and an operating temperature range from -22 to 140°F. It is UL, CSA, CE, and C-Tick approved for reliable use in commercial environments.
