How to Find the Right Valve

Numerous factors must be considered while selecting the appropriate valves for your application. Component sizing and selection can be complicated, but an engineer can begin the selection process by understanding the application requirements and locating the specifications that fulfil these criteria. The initial phase of this procedure is to consider essential device characteristics.

Media Type

The component’s material should be determined by the properties of the liquid or gas being regulated. Polytetrafluoroethylene (PTFE) and perfluoroalkoxy alkanes (PFA) are excellent options for monitoring harsh or corrosive substances, as they can tolerate these conditions. For maximum safety, it is imperative to utilise metal valves while monitoring pressured gases.

Eligibility Conditions

Identifying the ideal device for a given application is determining the right size. The wrong size might result in malfunctions inside the component or elsewhere in the system. Establish the temperature, pressure, and flow rate under which the component will operate. Metal pieces can withstand higher temperatures and pressures than their plastic counterparts.


Determine the function your component must serve. In a system, two-way pieces work well for on/off control, but three-way components may be utilised for on/off control in addition to media diversion and mixing. Consider whether it will be open or closed most of the time. Order one that is ordinarily oriented in this manner and reverses direction when activated to increase its lifespan.

Method of Action

Another factor to consider is how you will manipulate the component. Determine if you will manually operate it or if it will need to be automatically activated to turn off and on. If the latter option is selected, you must pair the device with an electric, pneumatic, or hydraulic actuator.

Maintenance Requirements

Ball valves are an excellent option for preventative maintenance since they are not susceptible to clogging and are very simple to repair. Three-piece has a body, a pair of end caps, and a stem. Because of this, the line doesn’t have to be turned off when the main body is taken out for cleaning without also taking the end caps off.

Performance Requirements

These devices need to be able to withstand changes in pressure and temperature. A good component will maintain its peak performance at the system’s lowest and highest temperatures and pressures.


Metal is preferable to plastic in high-pressure systems, especially when the operating temperatures are similar. Why? Because metals survive longer than plastics.


Sometimes fluid systems run at high pressures and temperatures, and sometimes they transport dangerous compounds that might represent a risk to workers if they leak. You should follow the best installation and operation practices, so fluid systems do not pose any unwanted dangers.


They are crucial for the safe operation of fluid systems. A safety shut-off or pressure relief component, for instance, can prevent your system from reaching an unsafe level of overpressure that could lead to a disaster. Because of this, choosing the proper component for the purpose you are attempting to achieve is crucial, which begins with a comprehension of how flow occurs inside your system.

Select Only the Best

To make your selection simpler and quicker, you must know where to begin. Having all the facts in advance can help you make a more confident decision.


Before making a decision, you must understand their chemical compatibility and operating conditions, as well as the application requirements of the system. This concludes the advice for picking the proper valves.
