 Lubricated Plug valve manufacturer in India


 Specialityvalve is the top  Lubricated Plug valve manufacturer in India. In lubricated plug valves, lubricants or sealants are used to make operation easier over a wide range of working pressures. Between the plug and the body is a lubricant coating. It necessitates regular lubricant injection. The lubricant should not be washed away by the fluid flow, should not pollute the fluid, and should be able to withstand line temperatures. In the plug valves, plastic sealants are employed. Effective sealants must have features such as resistance, flexibility, and the capacity to form a seal around each body part. The lubricant coating protects the metal surface between the plug and the body against corrosion.

What is a plug valve?

A quarter-turn rotational motion manual valve is known as a plug valve. It allows or prevents straight-through flow through the body by using a cylindrical or tapered plug (plug-shaped disc). Plug valves provide a straight path through the ports, allowing fluid to flow through the opening plug with the least amount of turbulence possible. The flow can be totally open or fully closed in either direction.


  1. Less force is required to open and close the valve
  2. The plug does not corrode
  3. Compatible with high temperatures and pressures
  4. Available in a wide range of sizes

Sleeved plug valve manufacturer in India


Speciality Valve is one of the largest sleeved plug valve manufacturer in India. A plug valve is the type of valve which is made up of conical or cylindrical tapered plugs that can control the flow of the medium by rotating inside the valve. These valves are used for a full flow system that is either fully open or fully closed. A sleeved plug valve is a quarter-turn non lubricated valve.

We serve plug valves in carbon steel, stainless steel, iron, and duplex steel. They all are very reliable for your industry needs. Our plug valve is appropriate for low steam pressure and oil/gas/water media. Our plug valve is a very good solution for any environment.
