Flow Control Valves

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. A water faucet is an example of a flow-control valve. Flow rate varies as a faucet handle is turned clockwise or counterclockwise. In a closed position, flow stops. Many flow-control …

Hydraulic Open-Center System

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 reservoir. Figure 2-3, shows this system in the neutral position. To operate several functions simultaneously, an open-center system must have the correct connections, which are discussed below. An open-center system …

Gear-Type Hydraulic Flow Divider

The gear-type flow divider functions like two gear motors with their shafts rigidly attached. We will consider first the case in which both motors have the same displacement. Since their shafts are attached, they both have to turn at the same speed; consequently, the same flow goes through both sides. Except for leakage, which is …

Orifice-Type Hydraulic Flow Divider

Theoretically, the orifice on both sides of the flow divider can be adjusted so that the ?P across the orifice plus the load ?P is equal on both sides. Then, the flow from the pump will divide equally, and both cylinders will extend at the same time. If the cylinders are the same size, they …
