There are distinct differences between casted and forged valves, and each type carries its own set of advantages and challenges.
Casted valves, as the name suggests, undergo a process called casting, where molten metal is poured into a valve mold and solidified. Once the molten metal cools and takes the shape of the casted valve, it is removed from the mold and goes through a finishing method. Castings or casted valves can be manufactured in complex shapes and intricate designs that can be challenging to achieve with forged valves. The design flexibility with castings can accommodate various combinations of configurations and sizes. Additionally, the cost-effectiveness of manufacturing a casted valve is generally greater, especially when producing larger quantities of valves.
Forged valves undergo a manufacturing process where metal is heated and shaped using compression. Forging sub jects&#; material to high pressure to create the valve shape and its grain structure is aligned to improve the mechanical properties of the component. The valve&#;s structural integrity comes from the grain structure; this allows for resistance to fatigue and stress. Forged valves typically result in fewer internal defects like porosity. These components are known for their strength, which is what makes them suitable for high-pressure and high-temperature applications.

When comparing the integrity of the two manufacturing processes, each has its own advantages and disadvantages. Casted valves tend to have lower strength and durability in comparison to forged valves. This is especially apparent in complex applications. Castings can also run a higher risk of having internal defects, as opposed to forged valves, which can impact the mechanical properties and the structural integrity of the valve. Forged valves, on the other hand, obtain limited complexity. These valves are most effective when the design and shape are simple. Forging can be higher in cost; it is generally more expensive to manufacture the forged valve.
The choice between casted and forged valves therefore typically depends on the specific requirements of the application and the trade-offs between cost, performance, and design complexity.
We can produce a variety of valve castings, including valve body casting and housing casting for ball valves, globe valves, safety valves, gate valves, butterfly valves, regulating valves, check valves, etc.
In the course of the casting valves process, we adopt superior materials: stainless steel, carbon steel, and other alloy steel. Our advanced casting processes such as investment casting and sand casting enable high-quality valve casting.
