Cast Iron Wafer Check Valve

Industries including water source projects, urban water supply and drainage, sewage treatment, electric power, petroleum, petrochemical, heat supply, shipbuilding, medicine, and metallurgy extensively utilize the cast iron wafer check valve. In water source projects, urban water supply and drainage, sewage treatment, electric power, petroleum, petrochemical, heat supply, shipbuilding, medicine, and metallurgy, the cast iron wafer check valve plays a vital role. Its versatile applications and efficient performance make it a crucial component in various sectors.

Wafer check valves are an effective solution to prevent water hammer and reverse fluid flow within water lines. These valves operate by allowing fluid pressure to open the valve plate when the flow is in one direction. However, if the liquid tries to flow in from the opposite direction, the valve plate impacts the seat, causing a cutoff in the flow rate. As a result, the flow is significantly reduced, enabling the torsion spring to close the plate without any fluid escaping through the valve. This mechanism ensures the prevention of water hammer and eliminates the risk of reverse fluid flow.

Installation between flanges can be done using various standards such as ANSI 16.5 CLASS 125 and 150LB, DIN2501 PN10 and PN16, BS4504 PN10 and PN16, and JIS 10K and 16K. These flange standards provide different levels of pressure ratings and are commonly used in different industries. For instance, ANSI 16.5 CLASS 125 and 150LB flanges are widely utilized in the United States, while DIN2501 PN10 and PN16 flanges are commonly found in European countries. Similarly, BS4504 PN10 and PN16 flanges are widely used in British industries, while JIS 10K and 16K flanges are commonly seen in Japanese applications. Regardless of the standard used, it is essential to ensure proper installation between flanges to ensure leak-free connections and maintain the integrity of the system.
