activator

The Evac Activator controls the discharge cycle of collected wastewater from fixture drains. The activator is one of the key components that comprise an Evac riser along with the buffer, interface valve, BVP valve, and vacuum hose.

Functions

  • Senses air-to-water pressure differential in the buffer
  • Controls timing of interface valve

Operation

The activator is designed to detect the change in head pressure from the buffer box. When activated, vacuum is supplied to the interface valve for a period of 2 to 3 seconds.

To aid in troubleshooting/maintenance procedures, the activator has a manual operator button that will open the pinch valve when compressed.
