These workhorses have the brute force to handle the
big job such as a heavy damper, globe valve, blast gate or air/gas
valve. It can be used for vortex control and hydraulic coupling and
will drive a speed changing screw or slide gate re-quiring 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.
