The Difference Between Cast and Forged Valves and How to Select the Best One for Your Application

Cast Vs Forged Valves

Valves are indispensable parts of the Valve Industry. The most common procedures for producing high-quality industrial valves are casting and forging. Both strategies have their pros and downsides. Forged valves offer superior strength and durability, while cast valves are often preferred for their lower cost and ease of use. This blog post will examine the difference between Forged and Casting Valves and which is best suited for your application.

Cair Euro Automation is the leading Valve Manufacturer in Ahmedabad, India. Offering the best quality of Motorized Valves, Manual Valves, and Electric Actuators.

What are Forged Valves

Forged Valves are made by heating a metal bar and pressing it into the correct form with a hammer or press. This technique aligns the metal’s grain structure and makes it stronger and less prone to failure. Forged valves are commonly used in high-pressure, high-temperature applications in which failure could lead to catastrophic requirements.

What are Cast Valves

Cast Steels have a chemical composition like Forge Steels, but as compared to forge steels they have worse mechanical properties, which can be improved by their heat treatment. Casting Valves are made by pouring molten into a mold and letting it cool. This process is relatively quick and cost-effective, it makes casting valves a popular choice for low-pressure applications. The advantage of casting is the ability to cast complicated shapes, which Forging can’t produce.

Difference Between Forged Valve and Cast Valve

Strength and Durability

For strength and durability, forged valves are the apparent choice. Because the forging process aligns the metal’s gain structure, thus producing a more resilient material. Thus, forged valves can withstand high pressures, harsh chemicals, and extreme temperatures without malfunctioning.

On the other hand, casting valves are less strong than Forged valves– the process of solidifying these valves sometimes leads to impurities such as voids and cracks in the valve. This method produces a material that is more porous and prone to breaking. Although casting valves can be produced with varied degrees of robustness, they are not typically recommended for use in high-pressure or high-temperature applications.

Cast and Production

Forged valves are expensive and energy-intensive to make. Labor costs constitute a large portion of the prices since the valve parts require extensive machining. In addition, they are produced in smaller batches compared to cast valves.

Casting valves offer several advantages, including cheaper costs and simplicity of production. The casting process is relatively quick and can be done in huge batches, which makes it a more cost-effective option for valve manufacturing. At Cair Euro Automation, we have Casting valves, available in a wide range of sizes and shapes, which makes them more versatile in certain applications.

Price

Forged valves are more expensive to produce because of the labor-intensive production process. However, they are frequently preferred in critical applications where dependability and durability are essential.

Size and Versatility

Forged valves are ideal for smaller valve sizes. It can serve larger sizes but will need to be developed in parts and connected by welding or flanges. This increases the risk of leakage. 

Cast valves are excellent for producing a wide range of valve sizes and intricate shapes.

Surface and Finish

The Forging Process produces a more refined surface finish, so there is less need for extensive post-forcing machining. On the other hand, the Forging process aligns the metal’s grain structure, thus producing a more resilient material. So, they can withstand harsh chemicals, extreme temperatures, and high pressure without failing.

Lead Time

Forged Valves have better performance as well as production time is longer. 

Cast valves are the best solution when time is a critical essence.

Conclusion

So, How to select the best one for your application– Forged Valves or Cast Valves? The answer is determined by several criteria, including the application, pressure, and temperature requirements, as well as budget constraints. In general, forged valves are the stronger, more dependable choice for high-pressure and high-temperature applications. However, if cost and simplicity of manufacturing are important considerations, casting valves may be a preferable option for low-pressure applications or when a large number of valves are required.

Ultimately, the choice between Forged and Cast valves comes down to your needs and requirements. As an expert in the valve industry, I encourage you to consult with a professional to determine the best solution for your project. At Cair Euro Automation, we have skilled professionals in the industry, who will help you to choose the best and suitable valve for your application.
