In the meter-out operation shown in Figure 6.39, the direction of the flow through the circuit is simply changed as can be made out from…

Meter-in is a method by which a flow control valve is placed in a hydraulic circuit in such a manner that there is a restriction…
Figure 6.35 illustrates the operation of a pressure-compensated valve. The design incorporates a hydrostat which maintains a constant 1.4kg/cm2 (20 psi) pressure differential across the…
This type of valve is used where the system pressures are relatively constant and the motoring speeds are not too critical. They work on the…
This is another type of flow control valve shown in Figure 6.31. It is made up of a ball with a through hole which is…
This is another type of flow control valve. It consists of a large disk which is rotated inside a pipe, the restriction in flow being…
This is the simplest form of a flow control valve. The globe valve gets its name from the disk element ‘globe’ that presses against the…
A flow control valve is a device used for adjusting or manipulating the flow rate of a liquid or a gas in a pipeline. The…
Although most direction control valves are of spool type design, other types are also used. One such design is the rotary four-way valve, which consists…
Flow control valves are used in constant-flow (fixed displacement pump) circuits to control actuator speed. The simplest type of flow control valve is a needle…
