Cast Iron and Ductile Iron Swing Check Valve

To prevent backflow in pipes, swing check valves are commonly installed. These valves operate as one-way valves, allowing smooth flow in one direction while automatically closing to protect the piping system, pumps, and other valves in case of flow reversal. A swing check valve consists of a hinged or shaft-mounted disc that swings to and fro. When there is forward flow, the disc swings away from the seat, permitting the passage of fluid. However, as soon as the flow ceases, the disc promptly swings back to the seat, preventing any reverse flow. It's important to note that the closure characteristics of the valve may be influenced by factors such as the weight of the disc and the force exerted by the return flow.

2.Test and inspection: MSS-SP-71, BS6755, DIN3230

3.Face to face dimensions: ANSI B16.10, BS5153, DIN3202 F1, and DIN3202 F6. Let's take a closer look at the face-to-face dimensions specified by these standards.
Firstly, the American National Standards Institute (ANSI) B16.10 provides guidelines for the face-to-face dimensions of valves. These dimensions ensure proper alignment between pipe flanges and valves in various industrial applications. ANSI B16.10 aims to standardize these dimensions for consistency and compatibility.
Next, the British Standard BS5153 also specifies face-to-face dimensions for valves. Developed by the British Standards Institution (BSI), this standard ensures that valve manufacturers and users in the United Kingdom adhere to consistent measurements. By maintaining uniformity in face-to-face dimensions, BS5153 facilitates smooth operations and interchangeability of valves.
Moving on to the German standards, DIN3202 F1 and DIN3202 F6 both address face-to-face dimensions. DIN3202 F1 specifies these dimensions for general-purpose industrial valves, while DIN3202 F6 focuses on the face-to-face dimensions of butterfly valves. These standards, developed by Deutsches Institut für Normung (DIN), ensure compatibility and enable accurate installation and replacement of valves.
In summary, ANSI B16.10, BS5153, DIN3202 F1, and DIN3202 F6 all provide guidelines for face-to-face dimensions in valves. These standards play a critical role in maintaining consistency, compatibility, and efficiency in various industrial applications. By adhering to these specifications, manufacturers and users can ensure proper alignment and optimal functionality of valves.

Our line of check valves come in a variety of features to best suit your needs. We offer bolted cover options for added security, and our swing check valves are available in both cast iron and ductile iron construction, with the latter also offering a 45 degree angle option. Our lift check valves also come in cast iron and ductile iron, while our ball check valves are available in both materials too. Our vertical check valves are another great option to consider. All of our valves come with seat ring options, including EPDM, NBR, brass, bronze, and stainless steel. For added convenience, we offer levers with counter weight as an option, and all valves come with epoxy coating for added protection.

The materials used for this application are cast iron GG25 (ASTM 126 CLB) and ductile iron GGG50 (ASTM A536).

The ANSI class 125 and class 150 swing check valves are constructed from either cast iron or ductile iron. These valves are designed to prevent backflow in pipelines and systems. Their structure allows them to swing open and closed to create a one-way flow of fluid or gas. The materials used for construction make them strong and durable, able to withstand high pressure and variations in temperature. They are commonly used in industrial and municipal applications. Whether cast iron or ductile iron, these swing check valves are a reliable component for maintaining the efficiency and safety of fluid and gas systems.
