Pulsed output control for steam valve
Download the full Specification
At a pre-determined interval the controller pulses its scum line blow down valve and measures the temperature and conductivity of the discharged boiler water.
If the conductivity is above the pre-set limit it will pulse the valve open and closed for a few seconds at a time until the conductivity (and hence TDS) falls to within limits, after which it waits for a predetermined time until the cycle starts again.
The bottom blow down valve and the steam header valve inputs have provision for micro-switch feedback which indicate to the controller the success or failure of the valve opening.
