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.
