In a wide number of applications, including in life science, pharmaceutical manufacturing, food and beverage production as well as the semiconductor production industries, plastics are becoming the go-to material when it comes to all types of valves.
One of the most popular options for the manufacturing of these high purity types of valves is polypropylene. The wetted surfaces of polypropylene valves can be coated with PTFE, which further enhances valve performance and non-reactive nature of the interior surfaces of the valves.
There are several other advantages to the choice of polypropylene valves. Carefully considering the application, the demands of the system, and the specific environmental or operating conditions ensures that plastic is the best option.
Solid Body Construction
The choice of polypropylene, which is a thermoplastic, allows for the valves to made through injection molding, creating a solid body for the valve. With this type of manufacturing, valves can be produced economically. Additionally, without a joint in the valve body, there is a limited risk of typical leaks or failures of joints, an essential consideration in high-pressure types of applications.
Lightweight and Durable
The choice of polypropylene valves provides a lightweight and durable component for any system. Lighter weight valves that are just as strong and durable as other materials put less stress on long runs of pipe, tubing, or hoses, which is helpful in system design and configuration.
The chemical resistant nature of the thermoplastic also makes it a good option for high purity types of applications. The additional coating of PTFE can reduce the friction on the surface of the valve, resulting in negligible pressure changes in the system even with multiple valves required.
High levels of fatigue resistance also make these valves a good option in mission-critical systems. With long duty cycles and reliable performance, these valves are a good choice for many industries and applications.
