The manufacturing of valves is a long process for such a basic piece of equipment. There are several steps to the manufacturing process including CNC machining, inspection, assembling, pressure testing, cleaning, packing, and storage. CNC machining, or Computer Numerical Control, is a short process which includes utilizing computers to control machine tools by using lathes, routers, mills, and grinders. CNC machining only produces the singular valve parts which are assembled after the inspection process.

During the inspection process, the valve parts are tested for air leaks, having the correct sealants, weight, and having the correct dimensions. Once these aspects have passed inspection, the valve parts are assembled. After assembly, the valves are placed under pressure testing which ensures the safety of the consumer, as well as the quality of the product. If the valves break during pressure testing than a new batch is made; if not, the valves will then be cleaned, packed, and stored for consumer use. While the valves are being manufactured the following are also all reviewed to endure the best product possible: the corrosiveness of the valve, flow, pipe size, valve temperature, installation constraints, envelope dimensions, accessibility, conformance to legal standards, and the tightness of shutoff that is required.

Despite contrary belief, the purchasing of valves can be a difficult process. There are several different types to choose from such as ball, gate, butterfly, check, control, plug, globe, regulator, relief, pinch, and diaphragm valves. Therefore, it is important to know which type of valve would be in the consumer’s best interest. There are also a multitude of end connections such as screwed, ranged, lugged, wafer, butt-weld, and mechanical joint. The end connections are important because they differentiate the strength of the valve. Depending on the project at hand, different materials may be better to use than others because of their resilience to pressure, weather conditions, rust, and other natural occurrences. Different materials of construction to consider are carbon steel, resins, steel or other alloys, or even cast iron.

The type of valve, motion required, rotary, linear, mode of operation, double acting, spring return, torque, power supply, frequency of operation also have to be considered. The types of valves are manual, electric, pneumatic, and hydraulic. Depending on the purpose of the valves some of these may better to use than others. It is also important to decide whether a quarter-turn, or multi-turn rotary will also be better for the situation. There are also two different types of spring return, including spring-to-closed and spring-to-open. There is also a choice between voltage power supply and available air supply. If other accessories are needed, for example limit switches, positioners, solenoid valves, transducers, and manual overrides, it is important that the valves will be compatible with these options.

Before choosing a valve it is also crucial to ensure there is an ample availability of replacement valves, actuators, or parts in case of a break down. Proper documentation should also be exchanged such as certified prints and dimension drawings to ensure the right product is purchased.
