The Automatic Discharge Device type WTAA is used to release the separated and permanently new accruing solids from the dirt collection chamber of the WTZA-Centrifugal separators or the WTSRF-Self Cleaning Filters. Suitable to fit the connection sizes of the drain ports the WTAA Automatic Discharge Device is available in different connection sizes from ¾“ - 1 ½“. There is a choice of different kind of connections like internal threads, flanges, TriClamp or welding nozzles. All discharge devices are equipped with a 2-2-way-membrane-valve and a controller-head. At the controller head you can find the connections for the com-pressed air ( 3-7 bar ) as well as the connection for the 24V/DC power supply.
The intervals and opening time to release the solids depends on the amount of solids and the particle size. There are 8 fixed programmed intervals which can be adjusted by dip-switches. Individual operation times can be programmed by factory. In manual mode two push buttons to open and close the valve are available.
