From Raw Materials to Finished Product: The Art of Valve Production
Produce a valve from raw material to finished product, there are several key steps involved in the manufacturing process. These steps include:
Design and Engineering
The first step is to design and engineer the valve. This involves creating detailed drawings and specifications for the valve, including its dimensions, materials, and functionality according to the customer’s requirements, especially critical in the customizations.
This requires the engineers to have rich technical knowledge and years of valuable experience in project practices. At DSNY Valve, we have a strong engineering team that works closely with our clients to ensure their specific needs are met.
Selecting Raw Materials
The next step in the valve manufacturing process is selecting the appropriate raw materials. The choice of raw materials depends on the type of valve being produced and the specific requirements of the client. Common materials used in valve manufacturing include cast iron, carbon steel, stainless steel, duplex steel, alloy steel, brass, and plastic.
Raw materials are a very important part of valve production, similar to the foundation of a house. Especially for casting materials, different casting processes will bring completely different quality castings. If the valve manufacturer is greedy for cheap and purchases unqualified casting raw materials, the problem may not be seen in the short term, but there will be great hidden dangers in long-term use.
Qualified castings need to meet the standards in all aspects of their chemical composition and mechanical properties. For example, the valves used in the field of oil & gas must be able to withstand the corrosive conditions, as the medium in oil & gas contains hydrogen sulfide (H2S) and other components, which are corrosive. Then the selection of raw materials is particularly important. The composition of key chemical elements, such as the ratio of S and P, should be strictly controlled during casting. If these two components exceed the standard, the hydrogenation resistance of the material will be insufficient. Reacting with hydrogen during long-term use may cause hydrogen cracking of the products, and may lead to leakage accidents.
While, the valves of power plants especially need to meet high temperatures and high pressure, and stainless steel is usually selected for its excellent mechanical properties. Then in the casting process, in addition to the control of the chemical composition, the qualified heat treatment process is also very important, which is one of the keys to ensure its excellent mechanical properties.
After the raw material arrives, we usually detect the chemical composition by spectrometer, and also detect its mechanical properties by Tensile & Charpy tests.
In addition, another important step of raw material selection is the initial inspection of castings before production, including whether there are quality defects such as trachoma and deformation on the appearance. If there are, they must be scrapped as soon as possible.
Processing and Manufacturing
After the inspection of raw material, the valve moves into the processing and manufacturing stages. This involves using advanced technology and machinery, such as CNC machines and other precision processing equipment, to shape and form the valve.
One of the challenges involved in processing and manufacturing is ensuring the valve is produced to the exact specifications of the design. This requires a high level of precision and attention to detail.
One important step is the inspection of each process before moving to the next one, which can help us to detect problems in the first place and correct them in time. At the same time, it can also help us save costs and improve production efficiency. So, a team of experienced technicians who oversee the manufacturing process to ensure each valve meets the required standards is the key.
In addition, there are some valves in special working conditions that require additional treatment, such as low-temperature valves used in the ocean. Except for an extended valve stem in design, a very important step before assembly after processing is to perform low-temperature pretreatment with liquid nitrogen with all parts. This step can check whether these parts have quality defects, and can also make them pre-deformed at low temperatures, so as to avoid quality problems such as leakage caused by low-temperature deformation of the valve after assembly.
Assembly
This step seems to be very simple and does not require any high technical requirements, but it is not the case. The experience and skills of an assembly worker are crucial to the quality and performance of the product.
For example, in soft seal ball valve assembly, the worker’s control of the valve seat size not only affects the sealing of the valve, but also affects the torque. A skillful worker can better save costs by avoiding repeated disassembly and assembly due to valve leakage, as well as improve valve performance and service life due to lighter torque.
Quality Control Testing
Once the valve has been processed and manufactured, it undergoes rigorous quality control testing. This involves using automated systems, such as pressure testing equipment, to ensure the valve meets the highest quality standards, including the hydraulic and air pressure tests of the valve shell and seats according to API 598.
Finally, visual inspection and dimensional measurement are also very important to ensure that the finished products meet the specifications.
Painting and Packing
At last, valves with cast iron and carbon steel will be covered with Epoxy paint to prevent them from rusting, unless customers have special requirements.
Before painting, there is another important step that is easily overlooked is the cleaning of the valve. In many cases, because of the oil and other dirty things on the surface of the valve have not been cleaned, causing the paint to not adhere and peel off. So professional cleaning equipment is very important, and ultrasonic is a good choice.
Finally, tidy up the valves, put them into a suitable export plywood case and take waterproof measures, and you’re done.
Delivery and Logistics
The final step in the valve manufacturing process is delivery and logistics. This involves working closely with clients to ensure the timely delivery of finished products. At DSNY Valve, we have strong partnerships with logistics providers to ensure efficient and reliable transportation of our products.

How to Control the Quality of the Casting Process?
Controlling the quality of the casting process is crucial to ensure that the castings meet the required standards and specifications. Here are some ways to control the quality of the casting process:
- Control the melting process: The melting process is critical in producing high-quality castings. The temperature and composition of the metal alloy must be controlled to ensure that the castings have the required mechanical properties. To achieve this, automated systems such as induction furnaces and electric arc furnaces can be used.
- Use high-quality molds: The quality of the mold used in casting also plays a significant role in the final product’s quality. High-quality molds made of refractory materials can withstand high temperatures and reduce the risk of defects such as shrinkage, porosity, and cracks.
- Control the pouring process: The pouring process is another critical step that must be controlled to ensure that the metal alloy is poured into the mold correctly. This includes controlling the pouring temperature, speed, and direction to prevent defects such as turbulence, gas porosity, and cold shuts.
- Conduct post-casting treatments: Post-casting treatments such as heat treatment or surface finishing can improve the mechanical properties and surface quality of the castings.
- Conduct regular inspections: Regular inspections, including visual inspection, dimensional inspection, and non-destructive testing (NDT), can help detect any defects or discontinuities in the castings and ensure that they meet the required specifications.
