The Manufacturing Process of Industrial Valves
08 Feb,2022

The manufacturing process of industrial valves is complex and includes many variables. The raw materials used in the manufacturing process are critical to the final product. The tools used to process the material affect the angle, geometry, and shape of the valve. 

To understand the manufacturing process of industrial valves, we must understand the different steps involved. This process consists of dissolving metal, cutting and shaping material, casting and cleaning up, and machine processing. The final product is tested for quality and tolerance, as well as temperature and pressure. 

Valve production can be further divided into various components, such as the manufacturing components and the actuation devices. The manufacturing process of a valve starts with the debarring of the valve body. Next, the technicians create threads so the valve parts can be attached to the pipe or component. Finally, the valves are tested for their functionality before being offered for sale.

What Are Industrial Valves?

Valve technology has improved the way people produce products. Valves are widely used in industrial settings and contribute to modern manufacturing. They are available in a variety of styles and materials and can turn liquids and gases on or off. Industrial valves are designed to handle difficult environments. They’re made of rubber, metal, and alloys and are designed to withstand extreme temperatures. 

When it comes to industrial fluid handling, choosing the right valve is crucial. In the manufacturing process, industrial valves undergo several processes to achieve their final form. Initially, the raw materials needed to produce a specific valve are collected. Next, the manufacturer contacts a supplier and requests the materials. Once this is complete, the team leader calls a quality assurance department to approve the final draft. From there, the process of manufacturing an industrial valve begins. 

The Manufacturing Process of Industrial Valves

Basically, this process includes four stages: order and design, inventory, and checklist. After a customer places an order, the manufacturing department will go out to find raw materials and procure them. It may take some time until all the steps are completed. Nevertheless, this process is not complicated and will give you a better idea of how the industrial valves are manufactured.

  • 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. 

  • 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 inventory. If the materials are not available in inventory, you need to procure them from suppliers. 

  • 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. 

  • 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. 

  • 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. 

  • 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. 

  • 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.
