PTFE Lined Plug Valve Manufacturer, factory and supplier. Various types of PTFE lined plug valve include 3 way PTFE lined plug valve, pneumatic PTFE lined plug valve and electric PTFE lined plug valve among others. The areas of applications of PTFE lined plug valve include pharmaceuticals, foods and beverages, chemical processing, sewage treatment, water supply, and petrochemicals among others. The advantages of using this valve are resistance to corrosion, fast operation, low initial cost, low-pressure drop, low maintenance, easy installation, cleaning and repair, and zero leakage. 

PTFE lined plug valve manufacturer produces this plug valve to operate using a handwheel/hand lever or by using actuators. PTFE lined plug valve is in the class of quarter turn valves. This means that the valve needs a quarter turn of the handle or actuator and then it will either start or stop depending on the direction of rotation. This characteristic makes this plug valve very fast and simple to operate. PTFE lined plug valve can be used in various applications such as foods, oil and gas, water supply, and chemical processing among others. 

PTFE lined plug valve is the plug valve that have the internal part covered with PTFE material. Due to the use of this PTFE material the valve becomes very resistant to corrosion as well as being able to withstand high pressure and high temperature. This type of valve is in the category of quarter-turn valves. This is because PTFE lined plug valve manufacturers design the valve such that it only needs a quarter turn of the handle to open or close the fluid flow. This valve is operated using a handle or by use of actuators such as hydraulic, pneumatic, and electric actuators. PTFE-lined plug valve manufacturers design this valve for on and off applications as well as throttling fluid flow. However, for throttling, this valve results in a lot of pressure drop and thus it should only be used if the piping system has very low-pressure drop.

PTFE lined plug valve component:


The handle in a PTFE lined plug valve is the part where one applies torque to open or close fluid flow. The handle is used in manually operated valves. For an automatic valve, an actuator is used. The actuator is tasked with providing the torque that the valve needs to open or close the fluid flow. 


This is the component that transmits the torque applied on the handle by the operator to the plug. PTFE lined plug valve manufacturer design the stem with threads that help the stem to rotate.


The plug is the component that helps to open or close the fluid flow. It gets the power to operate from the valve stem. It is connected to the stem through its top end. The plug has a port or more than one port which when aligned with the valve ports allows fluid to flow through the valve. 

Valve body 

The valve body is used to house internal parts of the PTFE lined plug valve such as the plug and seat. This component is usually made of very strong metallic materials such as carbon steel and stainless steel among others. This ensures the valve body remains very strong against high pressure as well as impact damage. The valve body also contains the inlet and exit ports of the valve that are connected to the pipeline. 

Body cover 

The body cover is placed on top of the valve body and as the name suggests, it helps to cover the body’s top part to prevent any fluid leakage. It is through the body cover that the valve can be opened for inspection and cleaning while it is still connected to the pipe. The body cover and valve body are made of the same metallic material. 


These components are used to prevent fluid leakage between the body cover and the valve body as well as between the pipe and the valve body connection. Bolts and nuts as well as screw threads are used to tighten the connection where the gasket is mounted.

How does a PTFE lined plug valve work?

A PTFE lined plug valve operates by rotating the valve plug for only a quarter turn. For the plug to make the quarter turn rotation, torque has to be applied on the handwheel or from the actuator. To start the valve, the handwheel is rotated for 90o degrees in the clockwise direction. This rotation from the handwheel is transmitted through the valve stem to the valve plug. This forces the plug to rotate for 90o degrees forcing its port to align straight to the valve port. As such, fluid starts flowing through the valve. To stop the valve, the handle is rotated in the counterclockwise direction for another quarter turn. This rotary motion is again transmitted to the valve plug via the stem. Due to this rotation, the plug rotates for 90o degrees becoming perpendicular to the valve port. This ensures the fluid is blocked and thus the valve is stopped. 

PTFE lined plug valve manufacturer designs this valve so that by rotating the plug slightly by around 45o degrees, throttling flow can be achieved.

3 way PTFE lined plug valve 

This is a PTFE lined plug valve with three ports. This type of valve is used in various applications that involve fluid mixing and fluid diversion. For fluid mixing, the fluid streams from two valve ports are mixed inside the valve body. After mixing, the fluid leaves the valve via the exit port as one fluid stream. When used to divert fluid flow, one fluid stream enters the valve and its direction of flow is changed inside the valve body to an angle of 90o degrees. This type of valve is very economical since it can serve the functions of three or two gate valves thus reducing the cost of the piping system.

Electric PTFE lined plug valve 

This is the type of PTFE lined plug valve that is operated by use of an electric actuator. This type of actuator uses electricity to operate. The actuator is placed on top of the body cover. The actuator is connected to the valve stem to help transmit power to the valve plug. The actuator has an electric motor that converts electrical energy to mechanical energy. This type of valve is very versatile as it can work in all areas of valve applications provided there is electricity. The valve is also automated such that it can open and close the fluid flow independently of a valve operator.

Pneumatic PTFE lined plug valve 

This is the type of PTFE lined plug valve operated by use of a pneumatic actuator. This actuator operates by use of compressed gas/air. The actuator consists of one or two chambers where compression of air takes place. The compressed air acts on a piston. This forces the piston to rotate creating mechanical energy. This mechanical energy (torque) is used to operate the valve stem and thus the valve plug. PTFE lined plug valve manufacturers recommend use of this valve in applications that have high demands of hygiene like foods and pharmaceuticals since the compressed air/gas used can be filtered. As such, it helps remove any impurities that may cause contamination to the product being manufactured.
