Cover flange

The cover flange is an essential mechanical component in many industrial valves, serving to connect different parts of a valve body. In control and shut-off valves, the cover flange often connects the valve body to the cover that seals the interior of the valve.

Function and significance of the cover flange

The cover flange plays a crucial role in maintaining the structural integrity and tightness of the valve. It ensures that the cover is firmly connected to the valve body so that pressure or medium (e.g., steam or gas) remains safely inside the valve. Proper connection of the flange is important to prevent leaks and ensure the safety and efficiency of the system.

Areas of application

Cover flanges are used in many types of valves, particularly in:

• Control valves: The cover must be removed to open, maintain, or inspect the valve. The flange allows for easy disassembly.
• Shut-off valves: Here, the cover flange provides a reliable seal to close the system and safely control the media.

Material requirements

Cover flanges are usually made of high-strength materials to withstand the high demands of industry. Not only must they withstand the pressure and temperature of the media inside the valve, but they must also be corrosion-resistant to ensure a long service life.

Summary

The cover flange is a small but crucial component in industrial valves. Its function of tightly sealing the valve cover and ensuring a tight connection contributes significantly to the reliability and safety of the entire valve system.
