Abstract
The present invention features a system for actuating additional fluid flow lines at a transfer station, without the continuous venting or bleeding of fluid. The transfer station operates its supply lines, or runs, at differential pressures ranging from 15 to 85 inches of water. It is desirable to maintain differential pressure in the primary line, or in the combination of primary and secondary lines at mid-range, at about 50 inches of water. The system of the invention entails replacing the existing constant bleed pneumatic controller with an electromechanical no-bleed controller.
