Product Description:
Valve Core Grease M810 is a lubricating grease specially designed for gas rotary plug valves. It remains durable under temperature fluctuations and can maintain stable torque over long periods. The grease exhibits minimal oil separation at high temperatures and excellent resistance to coal gas, making it suitable for a wide range of gas rotary plug valve lubrication applications.
This product is formulated with high-quality imported raw materials, including base oils, solid lubricants, and thickeners, using a proprietary precision formulation. Laboratory tests and practical application evaluations confirm that the grease performs reliably under temperature variations, maintains stable torque over extended periods, minimizes oil loss at high temperatures, and demonstrates excellent resistance to coal gas.
Applications:
-
Lubrication of gas rotary plug valves
-
Industrial equipment requiring stable torque under varying temperatures
-
Systems exposed to high temperatures and corrosive gases
