Air Receiver Automatic Drain Valve

Some compressed air auto drains work on the float principal.

Air receiver automatic drain valve.

Dva series automatic drain valve the dva automatic drain valve is designed to drain condensate from anywhere that condensate collects. Kingston model 620 automatic drain valve automatically removes the condensates that collect in the tank thereby extending the life of the air receiver and downstream air equipment. The reliable edv is a cost effective user friendly automatic electronic drain valve with a compact footprint. We are the leading manufacturer of auto drain valve for air compressor which are manufactured with high grade raw material.

The standard bowl for the auto drain valve is made of polycarbonate. When the liquid in the reservoir rises to a point where the float lifts off the seats control air pressure is sent to the pneumatic piston to open the normally closed ported ball valve. They work by allowing the condensate to gravity feed into the valves condensation reservoir. It is designed for use on all compressors with an unloader port.

There are four types of drain valve and there are pros can cons for each. A full ported solenoid valve is electrically timed by a solid state adjustable timer to provide off time operation from 1 to 60 minutes and on time operation from 1 to 10 seconds. These automatic drain valves are used when you cannot have any loss of compressed air. Effects organic solvents and chemicals and where these elements are likely to adhere to the equipment.

Each edv includes a y filter with mesh screen and ball valve to help prevent clogging. An air compressor auto drain automatically ejects these materials from the machine without user intervention making them convenient more efficient and can greatly prolong the lifespan of your compressor. Do not use in an environment where they are exposed to or come in contact with organic solvents chemicals cutting oil synthetic oil alkali and thread lock solutions. As the level of liquid in the reservoir drops the mechanical switch closes shutting off the pilot signal and closing the ball valve.

This all purposevalve removes condensate from compressors receivers dryers as well as from after coolers filters and drip legs. You need to fit a drain valve at the bottom of your air receiver on your filters and separators and at any point where water would tend to collect. Water tends to build up in compressed air systems.
