Cast Iron Check Valves

Cast Iron Check Valves are mechanical devices used to control the flow of fluids, typically in pipelines and plumbing systems. They are constructed from durable cast iron, making them well-suited for applications that require strength and resistance to corrosion. These valves operate based on the principle of allowing fluid to flow in one direction while preventing back-flow in the opposite direction. Cast iron check valves are commonly used in water supply, wastewater, and industrial systems to prevent the reversal of fluid flow, ensuring efficient and reliable operation while minimising the risk of contamination or damage to the system. Their robust construction and dependable performance make them a popular choice for various fluid control applications.
