The 1436 cPos Valve Controller is a pneumatic valve controller with the ability to precisely control parameters, such as flow, pressure and vessel level. These parameters are controlled independent of the main process control system. It can accept a 4-20 mA signal or digital inputs and using a PID loop algorithm, can precisely control the position of the valve with a total error of less than 1%. The controller can be mounted remotely or directly onto the valve.
