Do the moving parts of valve parts forgings need proper lubrication?

The moving parts of valve parts forgings do indeed require appropriate lubrication, especially in high load or frequent operating environments. Lubrication can not only reduce friction between components, but also effectively reduce the risk of wear, corrosion, and overheating, thereby extending the service life of valves and improving work efficiency. The moving parts of valves, such as valve stems, valve discs, and seals, undergo continuous friction and movement during the opening and closing process. Without proper lubrication, prolonged friction can cause surface damage to the parts, thereby affecting sealing and smooth operation.
The function of lubrication is not limited to reducing friction, it can also form a protective film to isolate the metal surface from direct contact with moisture and corrosive substances in the air or fluid, reducing the possibility of corrosion. Especially in environments with high temperature, high pressure, or chemical media, the moving parts of valves are more susceptible to corrosion and wear. Proper lubrication can effectively delay these adverse effects and maintain the reliability and stability of valve components.
In addition, the moving parts of the valve may gradually become ineffective or contaminated with lubricating oil or grease during long-term use, so regular inspections and timely replenishment or replacement of lubricants are necessary. Different types of valves and working environments also have different requirements for lubricants. Some specific applications may require the use of high-temperature, corrosion-resistant, or high viscosity lubricants, while ordinary industrial applications may use conventional lubricants or greases.
