Non Lubricated Plug Valve

Non lubricated plug valve Manufacturers in the USA is the type of the plug valve which is described to utilize a liner or sleeve of the non-metallic type in an attempt to reduce the friction developing between the valve body and plug.

Non lubricated plug valve Manufacturers Works as following
The sleeved plug valve operation is very simple but efficient enough. When the valve is in a closed position, the sleeve encases the plug completely; thus, it makes for a tight seal so that no fluid can cross through the valve. As soon as the valve is actuated to its open position, the plug partially or fully retracts, allowing fluid to pass through the annular space between the sleeve and the plug. The amount of retraction of the plug can be controlled, and this helps in regulating the flow rate quite accurately. It thus gives excellent throttling.

Advantages
Self-Lubricating Design: The elastomeric sleeve itself reduces friction in the area between the plug and the valve body, so there is no external lubrication.
Corrosion Resistance: Non-metallic sleeves have better corrosion resistance, which makes them suitable for handling aggressive fluids and for work in harsh operating environments.
It can create a bi-directional seal by flexible sleeve means it is leak tight irrespective of the direction of flow.

Components
Sleeve or liner: There is a non-metallic sleeve or liner installed inside the valve in a body cavity. This sleeve decreases the friction between the plug and the body.
Plug: A conical and well-honed plug resembles a wedge that shoves the sleeve into place against the body.
Body: The valve body contains the sleeve or liner as well as the plug.
