With advanced options in materials, industries now have a range of options to choose for materials used in parts and components. Many of these materials have advantages over the traditional material, including the use of polypropylene valves over stainless steel, bronze or other types of metals and alloys.
The use of polypropylene in the manufacturing of valves is not new, but it is also a relatively new option when compared to traditional metal types of valves. Polypropylene itself is an ideal option in high purity types of applications or in any type of systems where non-reactive materials are required.
Benefits of Polypropylene
One of the obvious advantages in the use of polypropylene valves is the lightweight nature of the material. Plastic valves are considerably lighter than metal valves of the same size, which means they are easier to position at any location in a system.
The manufacturing process used in creating plastic valves is through a molding process. This allows the valve to be manufactured in one piece, without a welded body. The solid design, results in no risk of a leak or a failure at a weld or joint, resulting in a more efficient and higher performing valve in any application.
The choice of polypropylene valves also allows for increased performance by adding a coating on the wetted surfaces of PTFE. Commercially marketed as Teflon, this surfacing of the interior of the valve means a longer life and greater resistance to even the most aggressive types of media in a system.
Polypropylene is highly durable even in environments where high and low temperatures are a factor for both the media in the system as well as the ambient environment. The exterior of the valve is also resistant to corrosion and damage from exposures to chemicals, moisture or even to UV light.
