Flow control valves are used to control the flow rate and hence to control the actuator speed.

FLOW CONTROL VALVES

• Flow control valves are used to control the flow rate and hence to control the actuator speed.

• The flow control valves use the following basic general symbols :

Orifice - Flow control valves unaffected by viscosity.

Throttle - Constitute resistance in a hydraulic system.

Rectangle - Indicates flow control valve.

Diagonal arrow - Indicates that the valve is adjustable.

• Table 7.5 presents the various standard symbols used for flow control valves.
