EFMB1/A/B-H Series Integral Type Small Quarter Turn Electric Actuator

Short Description:

EOM series electric actuator is a kind of motor rotation force through multistage reduction gear, worm gear and other mechanisms, and finally through the output shaft,in the form of rotation 90° to switch the valve device, mainly drive and control the Angle travel valve opening, such as butterfly valve, ball valve, plug valve, etc.Valve-like applications. EOM integration type torque range is 35-20000N.m. EOM series conventional electric actuator no clutch operation, durable,the stroke is stable and reliable, effectively improving the transfer efficiency.

Advantage

Warranty: 2 years
Overload Protection: The power will automatically shut off when the valve jam occurs. Thus preventing further damage to the valve and actuator
Operational Safety: F grade insulation motor. The motor winding has a temperature control switch to sense the temperature of the motor to protect the overheating issues, thus ensures the operational safety of the motor.
Voltage Protection: Protection against the high and low voltage situations.
Applicable valve: Ball Valve; Butterfly Valve
Anti-corrosion Protection: Epoxy resin enclosure meets NEMA 4X, customer-special painting is available
Ingress Protection: IP65
Fireproofing Grade: High temperature fireproof enclosure meets requirements in different situation
