Flow control valves, also known as volume-control valves, are used to regulate the rate of fluid flow to different parts of a hydraulic system.

C. FLOW CONTROL VALVES

FLOW CONTROL VALVES

1. What are Flow Control Valves ?

• Flow control valves, also known as volume-control valves, are used to regulate the rate of fluid flow to different parts of a hydraulic system.

• Since control of flow rate is a means by which the speed of hydraulic machine elements is governed, therefore flow control valves are also known as speed-control valves.

• The flow rate to a particular system component is varied by throttling or by diverting the flow.

2. Types of Flow Control Valves

The two basic types of flow control valves are :

1. Non-pressure compensated flow control valves, and

(i) Globe valve, and (ii) Needle valve.

2. Pressure compensated flow control valves.
