FOAM PROPORTIONER SYSTEM

摘要

An integrated around the pump (ATP) foam proportioning system that combines the venturi eductor, metering valve and shut-off valve into a single unit. Furthermore, the metering valve stem is contoured to make the flow read-out substantially linear. The display is also designed with movable components to display a single flow at the selected foam percentage rate.
