EFM/EOM SERIES QUARTER-TURN ACTUATOR

Fig No.: EFM / EOM series

APPLICATIONS
The FIVALCO EFM / EOM series is a quarter-turn electric actuator designed to regulate valves such as butterfly valves and ball valves. Equipped with a moisture-proof heater, over-torque protection, and motor overheat protection, this actuator delivers reliable and high-precision performance across a wide range of industrial applications, including HVAC systems, water treatment plants, power generation, and industrial water services.

FEATURES
Single-phase 230 VAC and 24 VAC / DC power supply while maintaining low energy consumption.
Manual or electric switching and a clutch-free design, allowing manual override via the handwheel.
Designed with an interchangeable spline sleeve to fit a wide range of valve stem, and a rotatable, replaceable ISO 5211 mounting flange to support versatile installation options.
To ensure safe operation, the actuator is equipped with a temperature sensor that monitors for overheating and activates an automatic shut-off in case of a jam.
Equipped with IP67-rated protection and a durable aluminum alloy housing coated with epoxy powder (IP68 is available on request).
