Nevertheless, this process is not complicated and will give you a better idea of how the industrial valves are manufactured.
Phase 1: Order and Design
Industrial valve production is the process of producing a high-quality industrial valve. This involves handcrafted components.
Once a valve has been designed and approved by the customer, it is time to place an order for it.
After a customer has approved a design, the provider places an order for it, and a predetermined deposit is made.
Once the order is placed, the manufacturing department starts sourcing materials and raw materials.
Phase 2: Inventory
Once the order is placed, the next step is to look for raw materials.
You need to manufacture different parts of the valves, so different materials are needed. You can look for the materials in the inventory.
If the materials are not available in inventory, you need to procure them from suppliers.
Phase 3: Completing the Checklist
After collecting all the raw materials, the manufacturing team has to create and checklist and check whether all the essential materials are present to start the production process.
Apart from that, the quality assurance team will also check the quality of the materials that are going to be used to manufacture valves.
Phase 4: Production Process
The production process of industrial valves involves the manufacturing of the valve bodies, stem, and seat.
The casting method is used to produce these parts of the valve.
Some manufacturers also use a forged method that involves cutting and forging, trimming, sandblasting, machining, and surface treatment.
The valve bodies can be made of a single piece or are cast using molds or cores. Modern casting processes use a core to produce parts with complex inner cavities.
Phase 5: Assembly
In the manufacturing process, it is essential to follow proper procedures for valve assembly.
The major components of the industrial valve should be cleaned and assembled separately.
After completing the production, the parts need to be assembled to create a complete valve.
The process of the valve assembly is generally carried out with the body of the valve serving as a reference part.
Phase 6: Pressure Test
After assembly, the valves have to go through a pressure test. The most basic pressure test for industrial valves is the hydrostatic pressure test.
The test involves partially opening the valve and applying a hydrostatic pressure that is 50 percent higher than its rated working pressure.
The valve’s sealing surface must remain leak-free, and the applied pressure cannot drop below its rated working pressure.
Phase 7: Inspection and Quality Control
The last step in industrial valve manufacturing is inspection and quality control. All the valves need to be inspected to make sure there is no leakage or error.
Industrial valve manufacturers should take inspection and quality control seriously. A QA is appointed to inspect the quality of the end product.
