Speciality Valve is leading Non Lubricated Plug Valve Manufacturer in India, provides tough, easy-to-use valves with tight shut-off and trouble-free operation. In applications where low maintenance and clean operation are crucial, non-lubricated plug valves are the preferred choice.

What is a Non-Lubricated Plug Valve?

A non-lubricated plug valve is a quarter-turn rotary valve with either a tapered or cylindrical plug. In contrast to conventional plug valves, it does not need any lubricant to seal the body and plug interface, making maintenance and contamination less likely.

Why Required?

Non-lubricated plug valves are best employed in situations where the product purity needs to be preserved, or where regular lubrication is inconvenient. They are applied when minimal emissions, low leakage, and ease of operation are crucial.

Key Components of Non Lubricated Plug Valve:

• Valve body
• Plug (typically PTFE-sleeved)
• Stem
• Seal rings
• Actuator or handle

Working of Non Lubricated Plug Valve:

When the actuator or handle turns the plug within the valve body, it opens or closes the passage for flow. Friction is minimized by a PTFE or similar non-metallic sleeve while also permitting an efficient seal without grease or oil.

Benefits of Non Lubricated Plug Valve:

1. Maintenance-free operation
2. Low-torque and smooth turning
3. No leakage from the outside
4. Cleaner for chemical or food-grade applications
5. Long lifespan

Functions of Non Lubricated Plug Valve:

• On/off control of flow
• Isolation of critical systems
• Flow diversion (with multi-port plug types)
