Figure 10.9 shows a circuit in which speed control in a hydraulic circuit is accomplished using a pressure-compensated flow control valve. The operation of the…
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 10.4 depicts a circuit used for unloading a pump using an unloading valve. In this circuit, the unloading valve opens as the cylinder reaches…
This circuit is designed as shown in Figure 10.2. When the four-way valve is in its spring-centered position, the cylinder is hydraulically locked. Also the…
