Pilot Signal Received

  • Condensation enters and collects in the water inlet of the valve.

Pilot Signal from Unloader

  • Piston shifts, closing off drain port. As the piston moves, it will open up the stainless ball check allowing condensate to be forced into the pressurized discharge reservoir.

Valve at Rest

  • When the pilot signal is relieved, the piston returns to a relaxed position. The ball check closes preventing zero pressure loss in the system. The drain port opens and the stored condensate is ejected.

Failure to routinely drain your compressor manually or by other means can contaminate compressed air systems and ruin your pneumatic tools and their application.

  • Attaches to the bottom of Tsunami Filters for operation
  • Made in USA
