About Lubricated Plug Valves
FlowBiz Exports Pvt Ltd is a High Quality Lubricated plug valve Manufacturer in Mumbai, Maharashtra, India. We are a leading manufacturer of Lubricated plug valve in Mumbai and nearby areas.
Lubricated plug valve consists of a cavity in the middle of plug along its axis. This cavity is closed at the bottom and fitted with a sealant-injection fitting at the top. The sealant is injected into the cavity, and a check valve below the injection fitting prevents the sealant from flowing in the reverse direction.
Advantages:
i Sealant helps create a renewable seal between plug and the body which prevents internal leakage.
i It also protects the seating surface against corrosion.
i It also acts as a lubricant and reduces force required to operate the valve.
i Lubricant pressure momentarily lifts the plug from the seat and makes it easy to turn.
i Also its high pressure assures no trapping of solids between valve body and plug.

Versatility for Multiple ApplicationsOur lubricated plug valves cater to a wide array of industries including oil & gas, petrochemicals, water treatment, and chemical processing. Their compatibility with various media-such as oil, gas, water, and acids-and wide temperature tolerance (-20C to 425C) ensures reliable operation in complex environments.
Reliable Sealing and Minimal LeakageEquipped with grease or metal seated sealing options, these plug valves deliver dependable shutoff performance with leakage classes up to Class V. The design adheres to international standards such as API 599, 6D, and API 598 for testing, ensuring safety, reduced emissions, and trusted reliability even in critical applications.
Customizable Design FeaturesCustomers can choose from different end connections (flanged, screwed, butt weld), body coatings (epoxy painted or anti-corrosive), and plug materials (matching body or specialty alloys) to suit specific operational needs. The three-piece or lubricated plug design and availability of manual, hand lever, or geared operation add further flexibility.
FAQ's of Lubricated Plug Valves:
Q: How does the lubricated plug valve enable online maintenance?
A: These valves are designed with a feature that allows grease injection while the system is still operational, making it possible to perform online maintenance. This minimizes process interruptions and ensures continuous reliability, especially important in critical applications.
Q: What sealing options are available and how do they benefit various applications?
A: The valves offer grease/lubricant seated or metal seated sealing options. Grease seating provides enhanced sealing for frequent operation, while metal seating ensures durability under high temperatures or abrasive media. Both options help reduce leakage, meeting Class IV or V leakage requirements.
Q: Where can lubricated plug valves be applied most effectively?
A: These valves are most effective in sectors such as petrochemicals, oil & gas, water treatment, and the chemical industry. Their corrosion-resistant build and pressure handling make them ideal for handling a range of fluids under challenging environmental conditions.
Q: What end connection standards can be specified for these valves?
A: Customers can select from ANSI, DIN, or BS standard end connections. The valves support various connection types including flanged, screwed, and butt weld, ensuring compatibility with global piping systems and project requirements.
Q: When should special alloy plug materials be considered over matching body material?
A: Special alloy plugs are recommended for applications involving aggressive chemicals, high temperatures, or fluids that could cause standard materials to degrade. These alloys enhance resistance to corrosion and wear, prolonging the valve's service life.
Q: How does the antistatic device improve valve safety?
A: The antistatic device, provided upon request, prevents static charge buildup between the plug and the valve body. This is particularly important when controlling flammable media, as it significantly lowers the risk of spark-induced accidents.
Q: What benefits do epoxy and anti-corrosive coatings offer for valve longevity?
A: Epoxy and anti-corrosive coatings shield the valve's body from environmental factors, chemical exposure, and moisture. This effectively increases the valve's lifespan, reduces maintenance needs, and maintains performance in harsh service conditions.
