V Port Ball Valves

V Port ball valves provide you with durable sealing. Thus, it is an excellent gas application that needs tight shutoff. It has either a ‘v-shaped body of the ball or ‘v’ shape designed seat. This allows the opening to be closed or opened in a controlled way, making the linear flow characteristic closer.

 Such a type of V Port ball valve is also known as a control valve because the flow velocity needs to be controlled according to the application. Dombor is a leading V port ball valve manufacturer that provides quality products such as v ball control valves in an affordable range. 

Structure of a V port ball valve:

Integral structure of the valve body:

Valves are side-mounted in both flag type or folder type V port balls. These valves have a robust rigidity, and therefore you do not need to worry about deformation and leakage.

The upper & lower self-lubricating bearings:

Both the upper and lower bearing if v port ball valves are self-lubricating. These are installed inside the valve body. The bearing has a large contact area with the valve stem. Hence, it has a high load capacity and a low friction coefficient. It also helps to reduce the torque of the valve.

Metallic hard sealing

Durable chromium is plated on the sphere, and the hard alloy is welded on the sealing valve seat that goes through hardening treatment like ion nitriding to enhance the life of the v port ball valve.

PTFE soft-sealing

PTFE valve seats have a great sealing performance as well as corrosion resistance.

Why does one need a V Port ball valve?

V port ball valves have many applications and markets. For example, these markets include transmission & storage, gas processing, and the industrial sector. V port ball valves are also used in the treatment of water, processing of foods in industry, transferring of acid in factories, agriculture, processing of waste, and pharmaceuticals. The stable flow control of V port ball valves facilitates such diverse applications of these ball valves.


Therefore, V port ball valves are suitable for the control of systems containing fiber & solid particles and liquid media such as acid, water, & others. 

V Port Ball Valve Sourcing Guide

Consider factors before sourcing from V-port ball valve factory so that you could find the best ball valve for your applications.

How Does a V Port Ball Valve Work?

A V-port ball valve works with a V-shaped bore. The valve can be operated manually using a handwheel or a chainwheel, or automatically, using an actuator. To open or close the valve, the handle is rotated, which in turn rotates the ball. The small end of the V bore opens first when the valve is open. Rotating the ball in the opposite direction closes the valve.

How to Choose a V Port Ball Valve When Sourcing

Here are some things you need to consider when choosing a v-port ball valve.

  • Pressure rating: Ensure you choose a valve with a suitable pressure rating for your application.
  • Valve size: Check the size of your piping system before selecting a valve to make sure you get the proper valve size.
  • The material used: Choose a v-port ball valve that is capable of handling the medium that is transported. Ensure the material of your valve is compatible with the media.
  • Temperature rating: The temperature of the application should be considered before selecting a valve.
  • Connection type: Choose a valve with a connection type that correlates with its application, such as flanged, welded, or threaded.
