A lubricated plug valve is a type of valve that controls the flow of liquids, gases, or slurries in a pipeline by rotating a plug. Lubricant is injected between the valve body and the plug to form a sealing film and reduce friction.
Features
Precision Sealing and High Pressure Application
The Lubricated Plug Valve can withstand pressures up to Class 2500 and temperatures ranging from -40°C to +450°C. A dense lubricant film forms between the plug and seat, maintaining extremely low leakage even under high pressure, high temperature, and corrosive media.
Low Torque and Long Life
The inverted pressure-balanced design with a lubrication chamber reduces opening and closing torque by approximately 60%, for example, ≤ 100 N·m for a DN200 valve. The lubricating film thickness of approximately 0.3–0.5 mm reduces the wear rate by approximately 80%.
Oil and Gas Industry
Used for controlling fluid flow and switching in oil and gas pipelines, ensuring safe and stable pipeline operation under high pressure and high temperature conditions.
Chemical Industry
Used for transporting corrosive, viscous, or toxic chemical media, ensuring precise and reliable fluid control in pipeline systems and reducing the risk of leakage.
Metallurgical Industry
Used in pipelines for transporting high-temperature molten metal gases or liquids, maintaining the continuity and safety of production processes.
Power Industry
Used for diverting and cutting off fluids in steam, water treatment, and cooling systems, ensuring stable operation of pipeline systems.
Pharmaceutical and Food Industry
Used for transporting high-purity liquids, preventing media contamination, and ensuring product quality and hygiene safety.
