In this system, a pump can rest when the oil is not required to operate a function. This means that a control valve is closed…
In this system, a control-valve spool must be open in the center to allow pump flow to pass through the valve and return to the…
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…
