(1) Ball valve 1 (2) Ball valve 2 (3) Ball valve 3 (4) Ball valve 4 (5) Ball valve 5 (6) Main control valves (7) Swing drive (8) Front of the machineThe ball valve assemblies have manually operated levers in order to control the flow of oil through the ball valve. Table 1 identifies the attachment circuit, the pump flow and the lever position for each ball valve assembly. The lever positions are shown in the following illustrations.Ball Valve (1)
Illustration 3 g00348016
(A) 1 Pump flow (B) 2 Pump flowBall valve (1) controls the lines for the one pump circuit and two pump circuit. With the lever in CLOSED position (A) , the one pump circuit is operational. With the lever in OPEN position (B) , the two pump circuit is operational.Ball Valve (2)
Illustration 4 g00348018
(C) Single action (D) Double actionBall valve (2) controls the front lines for the single action hydraulic attachment circuit and the double action hydraulic attachment circuit. With the lever in OPEN position (C) , the single action hydraulic attachment circuit is operational. With the lever in CLOSED position (D) , the double action hydraulic attachment circuit is operational.Ball Valve (3)
Illustration 5 g00349072
(C) Single action (D) Double actionBall valve (3) controls the front lines for the single action hydraulic attachment circuit and the double action hydraulic attachment circuit. With the lever in OPEN position (C) , the single action hydraulic attachment circuit is operational. With the lever in CLOSED position (D) , the double action hydraulic attachment circuit is operational.Ball Valve (4) and Ball Valve (5)
Illustration 6 g00349075
Ball valve 4 positions (C) Single action. (D) Double action.Ball valve 5 positions (A) 1 Pump flow. (B) 2 Pump flow.Ball valve (4) controls the single action pilot oil circuit and the double action pilot oil circuit. When the lever is in CLOSED position (C) , only the single action pilot oil circuit is activated. When the lever is in OPEN position (D) , the double action pilot oil circuit is activated. Ball valve (5) controls the one pump pilot oil circuit and the two pump pilot oil circuit. When the lever is in CLOSED position (A) , the one pump pilot oil circuit is activated. When the lever is in OPEN position (B) , the two pump pilot oil circuit is activated.Types of Manual Levers
