CTD is the culmination of years of manufacturing drains. It takes care of all problems normally associated with drains. The controller is now built with an ultra-reliable microcontroller and features dual adjustment of both cycle and drain. The valve has a large orifice and a special solenoid operator section to discharge dust.

Should the valve still get clogged you can service it without removing it from the installation. Press the knob at the bottom of the valve to mechanically clear all the sludge. Electronically flush a few times and now it is fully serviced and ready for use.
