ABSTRACT:
A micro flow control valve is interconnected between a main water line and a water distributing device, such as a mini sprayer. The interchangeable flow control valve is adapted to maintain a predetermined near constant micro flow rate of water to the distributing device within the approximate range of from 2.0 gph to 60.0 gph despite fluctuations in water pressure in the main water line. The control valve comprises a pin having at least one open-top channel defined at an outer surface thereof and a flexible diaphragm at least partially covering the channel. In operation, main line water pressure communicated to the control valve will function to flex the diaphragm into the channel to maintain such predetermined near constant micro flow rate in response to a variable pressure differential produced across the diaphragm. In carrying forth the method steps of this invention, the control valve can be removed from a housing and replaced with a second micro flow control valve having different flow rate characteristics. The second control valve will function to maintain a predetermined near constant second micro flow rate at an outlet thereof that is different from the first-mentioned micro flow rate.
