Everything Else

Speciality Valve is the leading Non Lubricated Plug Valve Manufacturer in India. The key feature of a non-lubricated plug valve is that its internal components do not require additional lubrication, making it easier to maintain and operate in sensitive environments.

How Does a Non-Lubricated Plug Valve Work?

A Non-Lubricated Plug Valve consists of a cylindrical plug with a hole or passage through it. This plug is positioned inside the valve body and is rotated to control the flow of fluid. When the plug's hole aligns with the inlet and outlet ports, the fluid flows freely through the valve. When rotated 90 degrees, the hole is blocked, stopping the flow. 

Benefits of Non-Lubricated Plug Valve

1. No Contamination: As the valve operates without external lubricants, there is no risk of contamination in sensitive industries such as oil and chemicals.


2. Low Maintenance: Without the need for constant lubrication, non-lubricated plug valves require less maintenance, which reduces downtime and operational costs.


3. Long Service Life: These valves are designed to handle high pressures and temperatures without wearing down quickly, leading to a longer service life.


4. Simple Operation: The design of non-lubricated plug valves allows for easy operation and reliable shut-off, making them ideal for on/off control applications.


5. Cost-Effective: Since there is no need for regular lubrication, these valves are more cost-effective over time, with reduced maintenance and operational costs.

Main Components of Non-Lubricated Plug Valve

• Valve Body: The body is typically made of durable materials like stainless steel or carbon steel, housing the internal components and ensuring robust operation in harsh conditions.


• Plug: The plug is the internal component with a hole or passage that controls the flow of fluid. It rotates to either allow or stop fluid flow.


• Stem: The stem connects the plug to the external actuator or handwheel, facilitating the rotation of the plug to control the flow.


• Seat: The seat provides a tight seal around the plug, preventing leaks when the valve is closed.


• Bonnet: The bonnet encloses the valve stem and provides access for maintenance or adjustments.
