Top Manufacturer of Lubricated Taper and Full Bore Plug Valve Flanged Ends and Threaded Ends Worldwide

Mayur (Valves) System Private Limited is a leading Lubricated Plug Valve Manufacturer — focused on delivering high-performance taper and full bore lubricated plug valves engineered for the most demanding oil and gas, petrochemical, refinery, and high-pressure industrial applications across global markets.

In oil and gas pipelines, refineries, and high-pressure industrial systems, valve choice is rarely a small decision. The fluids being handled — natural gas, crude oil, hydrocarbons, aggressive media, and high-pressure utilities — operate under conditions that quickly expose any weakness in a poorly engineered valve. Leaks, seal failures, jammed plugs, and inconsistent shut-off can quickly translate into safety incidents, production losses, and costly downtime.

This is exactly where a properly engineered Lubricated Plug Valve quietly outperforms ordinary quarter-turn valves. With its tapered or full bore plug design and dedicated lubrication system, it delivers strong shut-off, low operating torque, and reliable long-term performance even under the harshest conditions. At Mayur (Valves) System Private Limited, we manufacture lubricated plug valves built specifically for serious industrial duty — engineered, tested, and supplied to global standards.

What Is a Lubricated Plug Valve

A lubricated plug valve is a quarter-turn valve that uses a tapered or cylindrical plug as the flow control element. What sets it apart from other plug valves is the dedicated lubrication system — sealant is injected through ports between the plug and body, creating a leak-tight seal while also reducing friction during operation.

This unique design offers several practical advantages:

• Strong, bubble-tight shut-off even at high pressures
• Low operating torque thanks to the sealant film
• Reliable performance in high-temperature and high-pressure service
• Long service life with periodic sealant injection
• Suitable for clean fluids and gas handling applications

This is exactly why Lubricated Plug Valves have become the global standard for heavy-duty oil and gas, refinery, and high-pressure pipeline applications.

Taper and Full Bore Plug Valve Designs

We manufacture lubricated plug valves in both taper and full bore configurations, allowing project teams to select the right design based on flow requirements, pressure drop tolerance, and application duty.

Taper Plug Valve

A taper plug valve uses a tapered plug that fits snugly into the valve body. This design supports strong sealing under pressure, compact body construction, and reliable shut-off — making it widely used in oil and gas distribution and pipeline service.

Full Bore Plug Valve

A full bore plug valve has a port size equal to the pipeline inside diameter, allowing unrestricted flow with minimal pressure drop. This design is ideal for pipeline service where pigging, full flow, and lower energy losses are priorities.

Both designs are available with flanged ends and threaded ends, giving plant teams the flexibility to match the valve to different piping standards and installation requirements.

High Pressure API 6D Configurations

Our lubricated plug valves are designed in line with API 6D, the globally recognised standard for pipeline valves used in oil and gas service. We manufacture multiple high-pressure balanced configurations across pressure classes, including:

• Carbon steel API 6D industrial inverted high pressure balanced lubricated plug valve class 900
• Duplex API 6D industrial inverted high pressure balanced lubricated plug valve class 300
• Nickel alloy API 6D industrial inverted high pressure balanced lubricated plug valve class 600
• Stainless steel API 6D industrial inverted high pressure balanced lubricated plug valve class 1500
• Super duplex API 6D industrial inverted high pressure balanced lubricated plug valve class 2500

The API 6D industrial inverted high pressure balanced lubricated plug valve design is widely used in upstream and midstream oil and gas applications where high pressure, leak-tight sealing, and reliable operation are absolutely critical.

This range of material and pressure class options gives EPC contractors, pipeline operators, and project consultants the flexibility to specify the right valve for every line — from moderate-pressure utility service to ultra-high-pressure offshore and onshore applications.

Key Features of Mayur Lubricated Plug Valves

Major Valve Body Materials, Compositions & Applications

Choosing the right valve body material is just as important as selecting the right plug design. The body decides how well the lubricated plug valve handles temperature, pressure, mechanical stress, and environmental exposure across different plant and pipeline conditions.

Common Valve Body Materials

ASTM A351 gr. CF8M – 316 Stainless Steel Molybdenum steel with strong resistance to pitting in chloride solutions, plus excellent strength at elevated temperatures.

ASTM A216 gr. WCB – Carbon Steel Standard service material, usually supplied with CR13SS, stellite, or 316SS trim, with external coating for weather protection.

ASTM A216 gr. LCB Same corrosion properties as WCB, but preferred for low temperature ratings down to -46°C.

ASTM A351 gr. CF3M – 316L Low Carbon Stainless Steel Carbon content of 0.03% or less — ideal where annealing after welding is not practical.

ASTM A351 gr. CF8 – 304 Stainless Steel General-purpose, low-carbon, non-magnetic corrosion-resistant alloy. May be susceptible to chloride stress corrosion cracking.

ASTM A351 gr. CF3 – 304L Low Carbon Stainless Steel Can be used in as-welded condition without inter-granular corrosion concerns. Commonly used where field working is involved.

ASTM A351 gr. CN7M – Alloy 20 Superior resistance in 20–40% sulphuric acid service, with excellent corrosion resistance, mechanical properties, and fabricability.

ASTM A296 gr. CW-12M – Hastelloy C Outstanding performance in oxidising environments with strong resistance to pitting and stress corrosion cracking — even in weld joints.

ASTM A296 gr. M-35 – Monel Excellent resistance to many chemical applications and superior performance in saltwater environments.
