overview

FA-1000 series electric hydraulic drive actuator, suitable for floating point 3-wire control, with electronic locator, can also be used for 0... 10V or 0... 20mA control. It can adjust the stroke of the valve. They come with calibrated pressure switches, power failure safety mechanical devices, and a rotating crank for manual operation.

This actuator has a minimum force output of 700N and can be used on Johnson Controls VG8000, VBD, and VG7000 series valves, but it should be selected according to the rated closing force specified by the manufacturer.

When ordering FA-1000 separately, the minimum adjustable value is pre-set before leaving the factory for easy installation. Alternatively, the manufacturer can provide auxiliary switches and valve position feedback potentiometers.
