Control valves

The valves which are mainly used to regulate the flow of fluid in hydraulic circuits are known as “flow control valves”. The flow control valves are widely available in many different types according to their use. In hydraulics, flow control valves are used to control the amount of oil supplied to various parts within a hydraulic system. In this way, the momentum of a cylinder or the rotational speed of a hydraulic motor can be controlled.

Instrumentation Tools explains the working principles of control valve. Check out the Control Valve Working Animation with simple explanation.

In application of control valve, many terminologies are used and some Common Terms Used in Control Valves are actuator, trim, bonnet, bench set etc.

A valve is a mechanical device that controls the flow of fluid and pressure within a system or process. Basic Parts of Control Valves are Actuator and Body.

Classification of Control Valves: Globe, Gate, Butterfly, Check, Ball, Disk, Diaphragm, Linear motion, and Rotary motion Valves.

Examine the pneumatic control loops questions (transmitter-controller-valve systems) for an boiler, controlling both water level and steam pressure.

Study the Basics of Control Valves for different valve types like Gate Valves, Globe Valves, Needle Valves, Butterfly Valves, Check Valves, Plug Valves.

Before going to the globe valve, let’s try to understand the valve first. As we know, the fluid’s first and foremost property is to flow, and when it comes to regulating, controlling, or directing it, then one of the things that come into play is a valve. Valves can regulate or control a fluid’s flow.
