The process of valve manufacturing includes several steps. These steps depend on the type of valve and the process it will be used in. One common type of valve is a diaphragm valve, which is used for slurries. Another type of valve is a straight valve. Both types are used in the same process, but they differ from one another in some ways.
Valve bodies are typically plated with copper alloy to ensure a complete seal. After the plating process, the valves are painted with a type of elastomer. Finally, they are baked to bond the coating to the body. Once these steps are complete, the valve body is then tested in pressure. To perform this test, air with a pressure of six to eight bars is pumped through the closed valve for a period of time.
The valve body is often the largest component of a valve. The body connects all of the valve’s components. For example, a standard gate valve has three holes: an upstream port that flows material into the body, a downstream port that flows material out of the valve, and a third port that connects the bonnet and actuator.

The valve is also tested for leaks. When the valve passes this test, it will not leak as the pressure and volume increase. If it fails the test, the valve is returned to the warehouse. It’s important to note that there are two main types of valves: non-return valves and return valves. The difference is that a non-return valve allows fluid to flow in only one direction, while a return valve controls the flow of fluids in both directions.
If you’re looking for a valve with more strength and durability, you may want to look into forged valves. These are stronger than their cast counterparts and can handle higher temperatures and pressures. The forging process also reduces the chance of cracking and porosity.
The process of valve manufacturing involves many variables and different materials. The raw materials and tools used for the process are crucial to the final product. The tools used to process the material affect the shape, angle, and geometry of the valve. The process also involves dissolving metal, cutting and shaping, casting, and machine processing. When the final product is ready for sale, it is tested for quality and functionality.
After the design team approves the final design draft, the manufacturing team checks the materials for completeness. The quality assurance team also checks the materials to ensure that they meet the quality standards.
