Globe Valve Actuators
The Forta is a family of actuators for the control of 2 way and 3 way globe
valves.
The Forta has a very fine resolution PCBA board which ensures good
rangeability of the valve. The Software in the actuator calibrates the run-
ning time and S2 switch points to the valve stroke limits. It may also be
configured for different flow characteristics, inverse signal or sequence
control.
The U bolt mounting makes for a very easy and quick installation. The
manual override allows the actuator to be overridden and valve position
adjusted without disconnecting the power supply.
