Non- Lubricated plug valve manufacturers in India

Speciality Valve is a well-known Non- Lubricated plug valve manufacturers in India that offers good-quality valves engineered with reliability, minimum maintenance, and smooth flow control. Speciality Valve offers non-lubricated plug valves, which are optimally applicable in clean operation-based applications without applying sealing grease or lubricant.

What is it?

Non-lubricated plug valves are quarter-turn valves employed for tight shut-off and control of flow. Unlike lubricated ones, they utilize a sleeve or elastomeric lining on the plug in an effort to reduce friction and form a bubble-tight seal without the need for external lubrication. They are thus safe for the environment and suitable for sensitive applications.

Why Required?

These valves must be utilized in applications where contamination of the lubricant is unacceptable, such as food processing, pharmaceutical applications, and clean water applications. They are utilized because they can easily be operated, have less upkeep, and will perform well when being run repeatedly through an operating cycle.

Key Components of Non- Lubricated Plug Valve:

Body: Cast iron, stainless steel, or carbon steel

Plug: Cylindrical or tapered plug that rotates to close or open flow

Sleeve/Liner: PTFE or elastomeric sleeve to assure tight seal

Stem and Actuator: Manual or automatic operation

Sealing Mechanism: Sealing by pressure against the sleeve

Working of Non- Lubricated Plug Valve:

The valve is operated by a 90-degree rotation of the plug. The non-lubricated design relies on a soft lining between the plug and the valve body as seal and low-friction movement. No grease is used, ruling out contamination and reducing maintenance.
