Forta M700 - Spring Return
The TAC Forta M700 is a spring return actuator for the control of 2 and 3 way
globe valves.
It utilises the same PCBA as the Forta non spring return actuators and so has
the same capability with regard to self adapting to the valve stroke, and the same
flexibility with regard to set up configuration.
The U bolt mounting makes for a very easy and quick installation. A manual over-
ride is standard on all models.
