EFMB-1/2/3 Series Intrgral Type Quarter Turn Electric Actuator
The EOM series electric actuator is a highly efficient motor that uses various mechanisms like multistage reduction gear and worm gear to produce a rotational force, which enables it to rotate valve devices by 90° through its output shaft. It is mainly designed for regulating the opening angle of valves such as ball, butterfly, and plug valves. The EOM integral type has a torque range of 10-20000N.m and does not require clutch operation, making it highly durable and capable of delivering stable, dependable stroke that greatly improves transfer efficiency.
- Features:
- Warranty: 2 years
- Overload Protection: When a valve jam occurs, the power will shut off automatically to prevent additional harm to the valve and actuator.
- Operational Safety: A temperature control switch is installed in the motor winding to detect overheating, ensuring the safety of the F-grade insulation motor during operation.
- Voltage Protection: Protection is provided to safeguard against high and low voltage occurrences.
- Applicable Valve: Ball Valve; Butterfly Valve
- Anti-corrosion Protection: An epoxy resin enclosure that meets NEMA 4X requirements and can be painted according to customer specifications.
- Ingress Protection: IP67 is standard, Optional: IP68( Maximum 7m; Max: 72 hours)
- Fireproofing Grade: An enclosure that is both fireproof and able to withstand high temperatures, meeting diverse requirements in varying situations.
