The Kingston 620-3 Automatic Drain Valve automatically removes condensate that collects in an air compressor tank or receiver, protecting downstream equipment and extending the life of your air system. Its double-action design opens when the compressor starts and again when it stops, ensuring complete drainage with no manual intervention.
Built with a corrosion-resistant brass body and a stainless steel spring that closes the valve once condensate has fully discharged, the 620-3 delivers reliable, low-maintenance performance across a wide temperature and pressure range.
