The system comprises a solenoid switch and a manual switch, wherein an electrical wire extends from the valve to the control unit. The manual switch operates as a hand handling rotating lever; another use of manual switch is to serve as a means to force close the solenoid valve's outlet opening so as to provide a mechanism responsive to preventing automatic opening of solenoid valve controlled by control unit. ## Claims ### Claim 1 A valve apparatus oriented for irrigation system which is activated by a control unit; the valve apparatus comprises: a main body, a water inlet, a manifold, a water outlet, a solenoid switch and a manual switch, wherein the main body is a casing for building an assembly, the water inlet is disposed on one end of the main body, the manifold is a part that diverges into one or more than one water channels, wherein each manifold is internally disposed with said manual switch and said solenoid switch, which are characterized in that the manual switch is disposed at a position relative to the solenoid switch, the manual switch comprises: a rotating lever capable of axial rotation to regulate a valve to govern opening and closing of the water channels, wherein the rotating lever comprises a first gasket; the valve apparatus has a cylindrical shape, and has an opening, a plane, a closed portion, a second gasket and a blocking portion, the opening provides for water to flow from a first water channel to a second water outlet, the closed portion provides for closing the first water outlet to compulsorily turn off the solenoid switch so as to allow the manual switch to operate for compulsory shut-down or compulsory turn-on for water. ### Claim 2 (depends on 1) The valve apparatus oriented for irrigation system according to claim 1, wherein the rotating lever comprises a driver, base disc, shaft, and a positioning device. ### Claim 3 (depends on 2) The valve apparatus oriented for irrigation system according to claim 2, wherein the base disc is disposed with positioning holes to engage the rotating lever with the positioning device so as to keep the rotating lever retained in a secured position as the rotating lever turns. ### Claim 4 (depends on 2) The valve apparatus oriented for irrigation system according to claim 2, wherein the positioning device comprises a spring and a shrinkage peg, the shrinkage peg has an expansion portion and a shrinkage portion, an end of the spring is inserted into the shrinkage portion to push against the expansion portion, another end of the spring is inserted into a predetermined storage portion of the manifold, and the expansion portion is configured to protrude outwardly from an outer surface of the manifold after assembly is complete so as to allow a multi-tiered positioning capability for the rotating lever. ### Claim 5 (depends on 1) The valve apparatus oriented for irrigation system according to claim 1, wherein the rotating lever is disposed on an outer surface of the main body, and extends into an interior of the main body to form the base disc. ### Claim 6 (depends on 1) The valve apparatus oriented for irrigation system according to claim 1, wherein a shaft is disposed on another end of the rotating lever, and provides an axial portion protruding outwardly and to connect with said valve. ### Claim 7 (depends on 1) The valve apparatus oriented for irrigation system according to claim 1, wherein the first gasket is disposed to surround a grooved section of the shaft so as to prevent water leakage from a storage portion. ### Claim 8 (depends on 1) The valve apparatus oriented for irrigation system according to claim 1, wherein said second gasket is disposed to surround a grooved section of the valve apparatus having the cylindrical shape, which is operable to prevent water in the second water inlet from flowing into the water inlet and flowing into the second water outlet through the opening. ### Claim 9 (depends on 1) The valve apparatus oriented for irrigation system according to claim 1, wherein the water outlet is disposed with two stabilizers which provide the means for assembly in connection with a water leakage prevention device, wherein the water leakage prevention device has two grooved sections, such that when the water leakage prevention device is inserted into the water outlet, the two predetermined grooved sections operate along the stabilizers to serve as a track for guiding motions of the stabilizers. ### Claim 10 (depends on 9) The valve apparatus oriented for irrigation system according to claim 9, wherein the water leakage prevention device has a first end having an opening and directed to point toward the second outlet, a second end, and a third gasket which is inserted into the first end to provide for closing the second water outlet as a means for preventing water leakage. ### Claim 11 (depends on 10) The valve apparatus oriented for irrigation system according to claim 10, wherein an inner diameter of the third gasket, which is made of a soft plastic material, is substantially equal to an outer diameter of the opening of the first end, and is securely inserted into the first end which has protrusion on a surface of the first end.
