The Trident Auto Drain Valve–CTD works on the **principle of automatic removal of condensate from compressed air systems**. As compressed air passes through, moisture and oil collect in the drain chamber. A float or timer mechanism senses the accumulated condensate and automatically opens the valve to discharge it, while preventing compressed air loss. Once the condensate is expelled, the valve closes again to resume normal operation. This ensures dry, clean air supply, improves system efficiency, and reduces manual maintenance.
