WDV2-425

description

• The WDV2 Electronic Demand Drain Valves, with zero air loss, are suitable for all compressed air system applications from aftercoolers to filters to receivers to refrigerated dryers.These drain valves activate automatically and are both reliable and economical. Condensate (water, oil, and dirt) collect in the sump while the diaphragm is held closed by system pressure.As soon as the top sensor detects liquid, the solenoid energizes.The chamber above the diaphragm deflates and the condensate is driven out by system pressure.A timer is activated which allows a specific amount of condensate out and closes before any air is lost.If the unit gets clogged with a slug of condensate and scale, it will pulse to push that slug out of the valve and allow it to continue working properly.If the slug cannot be removed after a set period of time, an alarm light and contact will signal a problem.
