ABSTRACT:
A pneumatic circuit for controlling a liquid filler. A pilot air conduit conducts high pressure air to a pilot valve and a back pressure piloted valve. The pilot valve is normally closed so as to prevent the supply of liquid product to a container. High pressure air in the pilot air conduit opens the pilot valve to actuate supply of liquid to the container. A level sensor positioned above the container being filled provides a back pressure signal to the back pressure piloted valve causing it to exhaust the high pressure pilot air from the pilot air conduit causing the pilot valve to close.
