3 Way Non-lubricated plug valve manufacturer, factory and supplier. 3 Way Non-lubricated plug valve can be T port or L port design for mixing or diverting function. 3 Way non-lubricated plug valve is a type of plug valve that uses a sleeve between the body and the plug. The 3 Way non-lubricated plug valve sleeve is used to enhance smooth rotation of the plug without causing wear. This valve is very durable relative to the lubricated one and it can last for years without being replaced. 3 Way non-lubricated plug valve manufacturers design 3 Way Non-lubricated plug valve for use with a manual handwheel or by use of actuators. 3 Way Non-lubricated plug valve operates by making a quarter turn of the handwheel. This forces the valve plug to rotate aligning its plug port collinear to the valve port. As such, the fluid finds the valve open and thus flows. To close the valve, the handwheel is again rotated in the opposite direction where it aligns the plug port normal to the fluid flow path. This blocks the fluid from flowing through the valve.

What is a 3 Way Non-lubricated Plug Valve?

3 Way Non-lubricated Plug Valve uses a T port a L port sleeve component installed around the valve plug to maintain a continuous seal. The sleeve is used to provide the lubricity needed for the plug to rotate smoothly resulting in fast opening and closing of fluid flow. Sleeved plug valve manufacturers also use this sleeve to help reduce frequent maintenance needed in the lubricated type of valves as well as give the valve long service life. Sleeved plug valves are quarter valves. This is because they operate by turning the valve plug for a 90 degree angle to open or close. This type of sleeved plug valve operates manually or by use of actuators. 3 Way Non-lubricated Plug Valve is designed such that the plug moves up slightly when opening fluid flow to ensure it leaves some clearance with the valve seat to avoid wear which can reduce service life of the plug. 3 Way Non-lubricated Plug Valve has a tight shut-off and is used in various industrial applications such as waste water treatment, food processing, chemical processing, oil and gas among others.

3 Way Non-lubricated Plug Valve construction

In a 3 Way Non-lubricated Plug Valve, each component has its specific purpose for creating this robust valve design. The main components of a sleeve plug valve are the body, sleeve, cover, top seal, and cover are considered as main valve components.

Body: The body of a 3 way non-lubricated plug valve is cast as a one-piece that provides high integrity. This casting has integral design features that are important for creating key benefits of the product being cavity-free and maintenance-free.

The body casting has 360-degree lips around the ports which keep the sleeve in place preventing sleeve rotation while the valve is being operated. The sleeve relief area present in the body allows the PTFE sleeve to expand and contract during the temperature changes, this relief area also assists in controlling the valve torque.The body of the sleeve plug valve also consists of horizontal and vertical ribs which enables strong sealing capabilities between the sleeve and the plug by creating compression that is needed to maintain the sleeve in its place along with 360-degree lips.

Sleeve: A fluorocarbon sleeve that keeps the tapered plug in place and maintains a continuous seal. The sleeve provides the lubricity required to turn the valve, allowing it to open and close quickly, function without maintenance, be non-sticky, and last longer.

Top Seal: In 3 Way Non-lubricated Plug Valve design, the top seal ensures that fugitive emissions are kept to a minimum. It complies with or surpasses the most strict regulatory criteria currently in effect. The integrated, flexible graphite stem seal and the graphite cover seal ring ensure sealing where the stem and at the body/cover connects.

Cavity-free design: The cavity-free design is a significant feature of the product and is crucial in applications where solids are present in the media. The key valve components the body the sleeve and the plug are in close contact with each other creating the cavity-free design. This means that there are no spaces between the plug and the body that can trap media when the valve is being operated.
