Flow divider valve<\/strong>
\nValve which divides the oil flowing into the two hydraulic flow which has a different pressure than the source of power regardless of the pressure flow. This type of valve can be used to divide the flow of the hydraulic pump or source into two separate chain crawler tractor steering. Both of these series can operate, independently of the other. In industrial applications, where the flow should be divided with a very accurate or if the flow is divided into more than two streams, then there must be some means of rotary flow divider installed and connected to the hydraulic motor.<\/p>\n

Directional control valve<\/strong>
\nThe drain valve or stop the flow of oil flow so that the actuator can be operated to come forward or back and hold it in the middle, and dioperasikn with external power (manpower, solenoid or mechanical power).
\nDirectional valves are manufactured with many configurations depending on the number of doors and operating position but the valve is commonly used for the hydraulic circuit will be the valve spool type 2 posisis – 4 way (2\/4) or 3 positions – 4 way (3\/4). In earthmoving machinery, valves directionalnya for blade, dump body, buscket could have 4 positions (4\/4), the next position will provide a full cylinder float.<\/p>\n

Common center position on the 4\/3 way valve<\/strong>
\nFigure below shows about 4\/3 way valve with a wide range of middle position and is accompanied by a brief description of the method of operation:
\nCenter position valve 4\/3-way “recirculation pump” (tandem center).<\/div>\n

Ports P and T are connected: sehungga, pump discharge valve is only possible as opposed to a minimum and the resistance force (circulation pump = energy savings).
\nCenter position valve 4\/3-way “closed” (flashlight closed).<\/div>\n

Kempat this port closed: the placement of the power components is given, which in case of a slide valve, leaking oil is expected to position the components in the long term.
\nMiddle position “H” valve 4\/3-way (open flashlight).<\/p>\n
Four ports that interconnect: relif power components and hydraulic pump (eg. The cylinder can be changed).
\nCenter position valve 4\/3-way “power lines exhausted” (floating flashlight).<\/p><\/div>\n
