EA70-A Series Non-Spring Return Rotary Actuator

Brand: Eurotherm
Does not ship to United States

These Workhorses have the brute force to handle the big job such as a heavy damper, globe valve, blast gate or air/gas valve.

They can be used for vortex control and hydraulic coupling and will drive a speed changing screw or slide gate requiring a torque proportional actuator.

A solenoid brake holds the actuator in position when no movement is required.

These actuators stay in position when power is removed. NEMA 4 versions are available.

The EA70-A is compatible with the VB-7000 and VB-9000 valves in this catalog.
