How do industrial control valves work?

Industrial control valves are essentially powered by a control loop. They have a controller that signals them how to respond. A control valve can’t work by itself, it must receive a signal from an outside source, like an actuator or controller. A control valve is power-operated and it is used to control fluid flow by varying the size of the flow passage as directed by the signal in the controller. Control valves control flow, pressure, and temperature of the media. There are different variables that are measured for control, these include:

  • Flow
  • Liquid Level
  • Temperature
  • Pressure

Control valves come in really large sizes whereas pressure regulators are much smaller. Control valves can also have severe service trim material so they can operate in harsh environments. Because control valves have a controller, maintenance can look at the diagnostics and see if the valve is working optimally.

Benefits Of Using Industrial Control Valves

Industrial control valves have become a popular choice for a number of reasons including:

  • They are easy to install which saves considerable time and effort.
  • They can be operated automatically which removes the need for an operator to open and close the valve.
  • They can help limit obstruction and eliminate the possibility of clogging.
  • They reduce waste which makes them a more environmentally friendly option.
  • They have the ability to conserve a lot of water which can bring you savings on water or sewage bills.

Frequently Asked Questions

1. Which type of control valve is most commonly used in each industry?

One of the most common control valves used in each industry is globe valves. For globe valves, there are three different plugs that affect the flow or opening characteristics:

  • Fast opening
  • Linear
  • Equal percentage

The equal percentage globe valve is our most popular. It essentially has a plug that incrementally increases the flow rate by a certain percentage from the previous flow.

However, the type of control valve you need depends on the size of the pipe, the overall pressure of the system, the flowing media, process conditions, and other factors. Get in touch with us today for help selecting the right control valve.

Other common valves that we don’t carry include gate valves, pinch valves, or industrial diaphragm valves. Ball valves can also be considered control valves which you can find in our Marwin Valve line.

How does a control valve affect the control loop?

The control valve controls the fluid flow as it goes through the loop. The signal in the controller tells the control valve how much or little of the fluid should go through the system.
