Lubricated Plug Valve

MVS Valve offers a high-performance Lubricated Plug Valve engineered for reliable shut-off in critical industrial systems. Designed for use in petroleum refining, chemical processing, water treatment, and gas handling, our lubricated plug valves are built with a tapered plug mechanism that enables precise flow control and long-term sealing performance. With full metal-to-metal seating and a built-in lubrication system, the valve ensures smooth operation even under extreme pressure and temperature conditions.

The internal design features a single moving component—the plug—which, along with a continuous lubricating film between the plug and the body, ensures minimal wear and prevents contamination. This configuration is highly effective in resisting corrosion and avoiding leakage, especially in processes involving slurries or corrosive media. Manufactured in compliance with API 6D, ISO, and BS standards, these valves meet international performance expectations and are available with flanged ends in a wide range of materials and pressure classes.

we manufacture various options to meet demanding operational needs, including the API 6d industrial inverted high pressure balanced lubricated plug valve, suitable for heavy-duty applications. clients can also opt for high-grade variants such as the duplex API 6d industrial inverted high pressure balanced lubricated plug valve class 300 and nickel alloy API 6d industrial inverted high pressure balanced lubricated plug valve class 600, both engineered for enhanced corrosion resistance. for higher-pressure systems, we offer the stainless steel API 6d industrial inverted high pressure balanced lubricated plug valve 6d industrial inverted high pressure balanced lubricated plug valve class 1500, super duplex API 6d industrial inverted high pressure balanced lubricated plug valve 6d industrial inverted high pressure balanced lubricated plug valve class 2500, and carbon steel API 6d industrial inverted high pressure balanced lubricated plug valve 6d industrial inverted high pressure balanced lubricated plug valve class 900.

Every valve is manufactured with precision machining and stringent quality checks to ensure zero leakage and consistent performance. Whether operated manually or fitted with actuators, our lubricated plug valves guarantee strength, reliability, and long service life, making them a smart choice for industries that cannot compromise on flow control integrity.
