Auto Drain Valves

Due to cooling of compressed air, condensation of oil & water vapour takes place in Moisture Separators, Air Receivers, Filters, etc. Regular draining of these equipment is an essential maintenance function. By installing Auto Drain Valves, you can ensure that all equipment of the Compressed Air System get drained regularly without manual dependence, except for periodic checks. Low cost timer based ADVs are commonly used, but for larger Systems, zero air loss level based ADVs are used

Draining of Compressed air equipment such as Air Receivers, Moisture Separators, Filters, etc. is commonly done by low cost, timer - operated Auto Drain Valves. While these are effective in their functioning, they will open at the set time whether there is any condensate to be drained or not. This will result in loss of compressed air (and hence loss of energy), when there is no condensate to be drained.

The 'LEVEL SENSING Auto Drain Valve operation is level - based without any timer. The ADV has a Reservoir (in which condensate accumulates) connected to a drain valve which opens when condensate level reaches the top and closes when condensate level reaches the bottom. These operations are carried out by sensors placed at different levels of the reservoir. By this method only condensate is drained when the ADV opens and there is no loss of compressed air, resulting in saving of energy.

The reservoir & valve sizes are matched with the size and type , equipment to be drained, so that the ADV does not operate too frequently. Isolation valve & strainer are provided along with the ADV, for easy cleaning & servicing.
