The BENCO lift switch boom valve kit is a simple way to shut off the flow of liquid on your planter every time you lift the planter bar without complex and expensive electronics. The simple system uses a push-button lift switch (with the correct bracket for your planter) to shut off the flow through up to 2 boom valves.
When the row unit is raised, the lift switch is depressed and sends the signal to close the boom valves. This stops the flow of liquid. Your 12V pump will automatically shut off when 60 pounds of pressure is achieved in the system.
When the row unit is lowered again, the switch sends the signal to resume flow to the valves. As the valves open, pressure in the system drops below 60 pounds and the pump automatically resumes.
