1. A valve for regulating, as a function of ambient air having varying wind velocity and wind direction in an open-field control area, the distribution in a variety of patterns of a fluid in a fluid distribution system, the valve comprising:

  • a multi-port housing having an inlet for receiving a fluid, said inlet being in fluid communication with a stationary plate that cooperates with said housing to form a chamber, said stationary plate having a plurality of outlets therethrough disposed in a first pattern of outlets and at least one second pattern of outlets, said stationary plate further including attachment means for connecting each of the outlets in said first and second patterns, respectively, to a separate one of a plurality of tubes each having a respective distal end disposed adjacent the circumference of said open-field control area at a point spaced from other tubes in the plurality of tubes;

    a movable plate disposed in facing relationship with said stationary plate, said movable plate having a plurality of apertures extending therethrough disposed in a first pattern of apertures and at least one second pattern of apertures, said first pattern of apertures being selectively alignable relative to said first pattern of outlets and said at least one second pattern of apertures being selectively alignable relative to said second pattern of outlets, said first pattern of apertures having a predetermined orientation with said at least one second pattern of apertures;

    said valve further including rotatable means operatively connected to selectively rotate said movable plate to a predetermined number of positions relative to said plurality of outlets, whereby in a first of such positions all of the outlets in the first pattern of outlets are open and all of the outlets in the second pattern are closed thereby to equally distribute fluid to the open-field control area.
