Ball valve as a commonly used type of valve in the industrial field, its material selection directly affects its performance and scope of application. This article will give you a detailed introduction to the various materials of ball valves to help you better understand and choose ball valve products.
1. Overview of ball valves
Ball valve is a ball as the opening and closing parts of the valve, with simple structure, easy operation, good sealing performance and other characteristics, widely used in petroleum, chemical, natural gas, water treatment and other industrial fields. The main materials of ball valve include the following aspects:
1 ball material: ball is a key part of the ball valve, its material selection directly affects the sealing performance and service life of the ball valve.
2. Valve body material: The valve body is the main part of the ball valve, and the material selection determines the strength and pressure resistance of the ball valve.
3. Sealing material: Sealing material is the key to ensure the sealing performance of ball valve, and it needs to have certain wear resistance, corrosion resistance and aging resistance.
