10 Things You Should Know About Cast Iron Swing Check Valves.
Cast iron swing check valves are types of valves used in pipelines to regulate fluid flow. They have a disc that moves back and forth to open or close the valve. Unlike other types of valves, the cast iron swing check valve is pocket-friendly, durable, and low maintenance. Here are ten things you should know about cast iron swing check valves.
1. Material Construction.
Cast iron swing check valves are made of cast iron, a strong, durable, and cost-effective material. Cast iron is suitable for various applications, including pipelines and valves.
2. Operation.
Check valves operate automatically and do not require a human operator to open or close them. The disc moves back and forth in response to fluid pressure changes, allowing the fluid to flow through the valve.
3. Unidirectional Flow.
Check valves only allow fluid to flow in one direction, while they stop the fluid from flowing in the opposite direction. This feature ensures the valve's optimal performance as it prevents backflow.
4. Swing Type.
Swing check valves have a disc that swings from a hinge pin when the fluid flows through the valve, allowing the fluid to pass. When the fluid flow stops or reverses direction, the disc swings back to its original closed position, preventing the flow of fluid.
5. Flanged Connections.
Check valves come with flanged connections that facilitate easy installation and minimal maintenance. The flanged connections provide a secure seal that prevents leaks.
6. Various Sizes.
Cast iron swing check valves are available in various sizes, ranging from 2 inches to 36 inches, making them suitable for different types of pipelines and fluid flow capacities.
7. Corrosion Resistance.
Cast iron is naturally resistant to corrosion, which makes it a suitable material for gates and valves. Compared to other materials such as brass, alloy, or stainless steel, cast iron tends to hold up better over time.
8. Affordable Cost.
Cast iron swing check valves are pocket-friendly, making them a popular choice for many industries that require pipeline systems.
9. Durability.
Cast iron swing check valves are durable and can withstand harsh environmental conditions, including extreme temperatures and pressure.
10. Low Maintenance.
Check valves are low maintenance, have fewer moving parts, and require only periodic lubrication. This feature saves industries significant maintenance costs while ensuring the valves’ optimal performance.
Conclusion.
Cast iron swing check valves are an essential component of pipeline systems used in various industries, including petroleum, water treatment, and chemical processing. Their durability and low maintenance make them a popular choice for many industries. Knowing these ten things about cast iron swing check valves can help you make an informed decision when choosing the right valve for your pipeline system.
