Since a flow-control valve meters flow in one direction only, the inlet and outlet ports must be correctly connected in a circuit in relation to…
Flow-control valves are used to control an actuator’s speed by metering flow. Metering is measuring or regulating the flow rate to or from an actuator.…
These valves are used to control the direction of hydraulic flow by electrical means. A spool is shifted by energizing a solenoid that is located…
This type of valve is used to control the flow direction by using a pilot pressure. Figure 5-28, shows two units in which the spool…
This valve is used to control the flow direction manually. A spool is shifted by operating a hand lever (Figure 5-27). In a spring offset…
The four-way, sliding-spool, directional-control valve is simple in operation principle and is probably the most durable and trouble free of all four-way, directional-control valves in…
Figure 5-23, shows a typical four-way, poppet-type, directional-control valve. It is a manually operated valve and consists of a group of conventional spring-loaded poppets. The…
Four-way, directional-control valves are used to control the direction of fluid flow in a hydraulic circuit, which controls the direction of movement of a work…
A two-way valve is generally used to control the direction of fluid flow in a hydraulic circuit and is a sliding-spool type. Figure 5-21 shows…
Check valves are the most commonly used in fluid-powered systems. They allow flow in one direction and prevent flow in the other direction. They may…
