Intellisys® Three-Position Controller for Local and Remote Valve Operation

Our three-position controller is based on the Intellisys motor technology and can be fitted to most Nor-Cal Products valves including pendulum, gate and butterfly types. When operated stand-alone with simple, discrete I/O from the host system, the valve can be opened, closed or moved to a single, user-set intermediate position, providing a method to control chamber pressure in a lower cost and less dynamic manner than closed-loop downstream pressure control. The controller can also be used with an RS-232 communications link for multiple user-set positions.
