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…
Figure 10.10 shows a mechanical hydraulic servo system with automotive power steering, the sequential operation of which occurs as follows: • The input or command…
Fail-safe circuits are basically designed to prevent injury to the operator or damage to the equipment. In general they prevent any accidental fall or overloading…
From our earlier discussions, we have seen how a sequence valve can be used to create sequential operations in a hydraulic circuit. The circuit depicted…
Figure 10.5 illustrates the use of a counterbalance or backpressure valve to keep a vertically mounted cylinder in upward position during pump idling. The counterbalance…
Figure 7.26 is an illustration of a common type of water-cooled heat exchanger used in hydraulic systems. This is typically a shell and tube-type heat…
Figure 7.25 shows an air-cooled heat exchanger. The hydraulic fluid to be cooled is pumped through the tubes that are finned. As the fluid flows…
