Working in an industry where systems need to be maintained to strict standards means that care must be taken in choosing the most basic to the more complex parts and components. One of the elements of these systems that need to be considered is the use of high purity valves.
Any type of standard application valve can be found in high purity valves. These valves are manufactured from materials that are selected due to their non-reactive and corrosion resistant nature. A top example of a material for these types of valves is the valve body made out of highly durable polypropylene and PVDF (polyvinylidene difluoride) and then coated with PTFE for the wetted components. This provides an extremely rugged valve in any system with the benefit of PTFE (polytetrafluoroethylene) to prevent any type of corrosion or collection of material within the valve.
System Considerations
In systems with high temperatures and high pressure, the use of PTFE and polypropylene or PVDF is also an important consideration. These materials offer a long life cycle in any type of valve from ball, globe or gate to check valves and valves to regulate the flow through the system.
In some instances, standard valve designs and sizes may not be the right option for the system. Rather than creating complex configurations to accommodate standard sizes of high purity valves, opting for custom valves is often the most cost-effective option.
When choosing custom valves, always work with a company that specializes in high purity products. These companies typically provide full support for engineering services for the valve and work closely with your in-house team to provide just the configuration needed for the system.
This ensures that the valve is produced to meet the standards required and that the manufacturer has experience in designing and manufacturing valves and other components specifically from PTFE and other high purity materials.
