In any type of high purity system, each component has to be carefully considered and selected to maintain the high purity process. This means taking the time to not only select the correct type of valves but also considering how the system components integrate together.
Different types of processes, including food and beverage production, pharmaceutical products, and in cleanroom types of applications, each of the high purity valves, are selected for the type of control required. In addition to the standard options and valve configurations, custom options in valves may also be an important consideration to meet different operating conditions.
The operating conditions for the system have to be known to choose the best option in high purity valves. This includes the high and low-pressure limits for the system, the temperature of the media, the ambient or environmental operating temperature as well as the flow through the system. The specific characteristics of the media, including the viscosity, if solids are present and any corrosive materials in the media should also be known before choosing a valve.
Valves can have different requirements in a system. For example, ball valves are typically used for on and off operation of a system, but they can also be used for general flow control in some applications. Other valves, such as check valves, work automatically, and are used to prevent backflow through a system
Metering valves are the ideal choice when there is a need to carefully control the flow of the media through the valve. Each of these valves, in turn, can be controlled manually, through a solenoid or in pneumatic applications.
Different options in ports and connections, mounting options for the valves, as well as the types of seals and components used in the valve are also important factors to consider when choosing the right high purity valves for the job.
