Common Cast Iron Valve Parts

1. Valve Bodies: The main structure that houses the internal components and provides the pathway for fluid flow.

2. Bonnet: The cover that encloses the valve mechanism, often bolted to the valve body to allow for maintenance access.

3. Discs and Gates: The components that control the flow of fluid, such as gate valves or globe valves, which can be made from cast iron for strength and reliability.

4. Seats: Provide a sealing surface for the valve disc, often designed for easy replacement when worn.

5. Stems: Connects the valve handle or actuator to the internal disc or gate, allowing for precise control of flow.

6. Flanges: Used to connect the valve to piping systems, ensuring a secure and leak-proof fit.

7. Actuators: While not always cast iron, some actuators are designed with cast iron components for added strength and durability.

Benefits of Cast Iron Valve Parts

• Strength and Durability: Cast iron is known for its high tensile strength, making it suitable for heavy-duty applications.
• Cost-Effectiveness: Generally more affordable than materials like stainless steel, making it a popular choice for various applications.
• Heat Resistance: Cast iron can withstand high temperatures, making it ideal for steam and hot water applications.
• Machinability: Can be easily machined to create precise shapes and fittings, ensuring a proper fit in various valve designs.

Applications

• Water and Wastewater Treatment: Commonly used in valves for controlling flow in municipal systems.
• Oil and Gas Industry: Essential in pipelines and refineries for controlling the flow of fluids.
• Heating Systems: Often found in heating systems for controlling steam and hot water flow.
