How Does Any Hydraulic Flow Control Valve Function?

To regulate the pressure and flow rate of liquids or gases through various pipe lines, flow control valves are used. For optimizing any performance of the system, it is essential to use flow control valves. That is dependent on flow control in a variable flow area.  Let us try to understand how hydraulic flow control valve functions and what are the considerations for selecting the right hydraulic flow control valve for any application.

How does it work?

There are many unique designs available for flow control valves for different sets of applications. Therefore, understanding their work is important for choosing the right type of valve for any kind of application. Following are few common types of flow control valves.

• Diaphragm
• Ball
• Butterfly
• Needle
• Plug
  
  
  

When you look at the hydraulic circuits, there are number of different hydraulics parts used for controlling the flow and actuation of sophisticated electronic controls.

·         Flow regulators

·         Orifices

·         Bypass flow regulators

·         Pressure compensated variable flow valves

·         Demand compensated flow controls

·         Deceleration valves

·         Priority valves

·         Flow dividers

·         Proportional flow control valves

·         Proportional flow logic valves

·         Rotary flow dividers

·         Pressure compensated proportional flow control valves

To control the flow rate of fluid, control valves have aperture that may either open or close to increase or decrease the flow rate. The simplest option for this is ball valve. Ball has got hole at the centre and as the handle is turned, the hole gets aligned at the opening of valves so that it can allow the flow of liquid. If you want to stop the flow, the handle is used in such a way that it positions perpendicular to the hole position and the flow of fluid is obstructed.
