SV Series - Stand-Alone Electronic Products
The SV Series Positioners were designed specifically for use with Exlar rotary and linear actuators to control valves and dampers in process control applications. The all-electric design eliminates the complexity of applying electro-hydraulic interface pilot valves or electric-pneumatic positioners, and provides two-way communication between your system and the actuator.
The fully digital SV Series Positioners operate from standard process control inputs allowing for simple retrofits of hydraulic or pneumatic actuated valve applications or dampers. SV Series Positioners used with Exlar's high performance linear and rotary actuators can also replace fluid power and low performance electric actuators, eliminating problems associated with actuator failures.
