DIN Cast Iron Ball Valve is a type of valve with a body primarily made of cast iron. Its core component is a ball with a passage, which controls the flow of fluid by rotating the ball to open, close, or regulate the flow. This type of valve is commonly used in piping systems for switching or flow control. The cast iron material offers good cost-effectiveness and practicality, making it widely used in industrial applications.
The main components of a cast iron ball valve include the body, stem, ball, sealing ring, and actuator:
Body: The main structural part of the valve, typically made of cast iron (such as gray cast iron or ductile iron), providing strength, corrosion resistance, and structural support.
Stem: Connects the ball to the handle or electric actuator, transmitting the operating torque.
Ball: The core component that enables opening and closing through rotational movement. A high-precision machined ball is used for flow control, and its surface may be chrome-plated for enhanced wear resistance.
Sealing Ring: Usually made of rubber, PTFE (polytetrafluoroethylene), or other high-performance materials, installed on the sealing surfaces between the ball and seat to prevent medium leakage.
