CNM VALVE is a leading Plug valve manufacturer in China, which offers a range of plug valves to suit a broad a variety of applications, reliably addressing the vast majority of requirements.


A Plug Valve is a flow control device designed to regulate the flow of a liquid or gas within a high-pressure system. As well as controlling flow via basic moderate throttling, plug valves can be used in on/off position or to divert flow or combine flow.

 

Plug valves are a mechanically simple valve that utilises cylindrical or conically tapered "plugs" which rotate inside the valve body to control flow through the valve. The plugs within the valve contain one or more hollow channel that cuts sideways through the plug, this allows fluid or gas to flow through the plug when the valve is open. This simple mechanism and ease of operation mean that plug valves are often economical.


There are two typical types of plug valves, which are lubricated and non-lubricated. The seat is an integral part of the body in terms of lubricated plug valve. For non-lubricated plug valve, there will be lined and sleeved type, with a soft seal design to improve leakage tightness of the valve. 


Plug Valve Advantage:

  • Economical and easy to maintain

  • Ensure the integrity of the seal even in the most extreme conditions

  • Simple design with few parts

  • Quick shutoff

  • Maintenance and repair can be done at the place of operation

FAQ

  1. Different types of Plug Valves:

    There are two typical types of plug valves, which are lubricated and non-lubricated. The seat is an integral part of the body in terms of lubricated plug valve. For non-lubricated plug valve, there will be lined and sleeved type, with a soft seal design to improve leakage tightness of the valve. 

  2. What is the difference between a plug valve and a ball valve?

    A ball valve has a spherical disc with a hollow centre, and a plug valve has a cylindrical or conical disc with bored passages going through it. 

    Both valves have similarities, including their closing and opening mechanisms and the flow-directing possibilities in multi-port plug valves are similar to the possibilities in corresponding multi-port ball valves. One of the main differences is the disc in a ball valve is smaller in size than the disc in a plug valve.
