What is a V-port Ball Valve?

What is a V-Port Ball Valve? When it comes to ball valves, the V-port ball valve plays an important role in the valve world. This V-shaped ball or V-shaped seat is utilized with higher velocity applications that would otherwise damage a normal ball valve. These ¼ turn control valves can be flanged or non-flanged. The seats can be rigid or flexible metal or PTFE which is a synthetic fluoropolymer better known as Teflon.

The V-port ball valve is also used when precision cannot be sacrificed because corrosive liquids (clean or dirty) or gases going through the piping system need to be sustained to critical and controlled specifications.

It is imperative that you provide the following specifications to a quality and knowledgeable valve company so not to over or under-size your V-port ball valve:

  • Description of your application
  • Type & pressure of media
  • Temperature
  • Flow Rate
  • Inlet pressure
  • Line Size
  • Pressure Drop

Failure to report accurate specs can risk the success of your line. If you over-size your valve, the pressure drop will not be accurate and will affect the flow through your handling system. If under-sized, you will over work the pump on the system.

Where a normal ball valve is normally used as a on/off valve, the V-port ball valve can be used as a control valve in high pressure applications.
