The TVC Positioner is designed specifically to provide precise valve positioning control of hydraulic quarter-turn or linear valve automation systems using either on-off or proportional solenoid valves. The TVC Positioner can accept positional feedback from a three wire potentiometer or a position transducer with a current output.


Precise positioning of any quarter-turn or linear valve or mechanism.
