Choosing an Industrial Valve

All applications require a specific valve type to maximise the functioning of a pump system. There are so many valve types and so many factors to consider but definitely no ‘one-size-fits-all’ approach. Here is a brief outline of how to choose the correct valve.

Industrial Valve Types

Before getting started, check out some of the common valves available:

  • Gate Valves
  • Rotary Ball Valves
  • Globe Valves
  • Ball Valves
  • Disc Check Valve
  • Butterfly Valve
  • Needle Valve

What to Consider

With so many elements, designs and functionalities, choosing a industrial valve can be quite an arduous undertaking. Here are a few aspects to consider when selecting the right valve.

  1. Application Criteria

The medium you will be pumping – liquid, gas or solids – will be the first determining factor when it comes to valve choices. The valve flow coefficient (Cv) is a useful tool as it combines the effects of all flow restrictions within the valve, into a single number. These take into consideration factors such as liquids being incompressible while gases are compressible; fluid temperature and piping size.

  1. Valve Function or Process Conditions.

You should have a basic idea of how the valve will function – open most of the time or closed? Will it control the flow? Is it two-way, three-way or multi-purpose? What is the capacity of the flow? All these elements will come into the initial valve choosing.

  1. Valve Control Form

The valve’s control form specifies the type of control action for the valve assembly. There are six different control forms to choose from so make sure to get this right first off.

  1. The Linkage Kit

In addition to the correct valve, it’s important to get the correct valve/actuator combination – these are outlined in detail in various Valve Assembly Tables.

  1. Valve Assemblies or Valve Components

Once you’ve chosen the valve body, actuator and linkage, decide whether to order them separately or fully assembled. Just ensure that you have selected the correct elements before ordering.
