Types and Uses of Plastic Valves

Valves are devices that help in controlling the flow of substances which pass through various structures and fittings arranged in a commercial as well as household environment. They help in appropriately maintaining the opening, closing and obstructing passage ways. Valves are generally made from metallic or plastic materials.

Plastic regulators are made from polymers of acetal. As the material helps to deliver excellent resistance against stress, chemical reactions, fatigue and provides premium lubrication. Other materials and the properties they offer are listed below.

• Polyvinylchloride (PVC) is used in making regulators of this kind as the material is non-toxic, flexible and is smooth in physical appearance. 
• Chlorinated polyvinyl chloride (CPVC) has tremendous resistance against temperature; hence this material is used in regulators which are subjected to high temperature and pressure. 
• Polytetrafluoroethylene (PTFE) as the material does not chemically react with any substances and has low friction. • Polyethylene (PE) is a combination of robust, flexible plastic. This material is also resistant to temperature, stress ultraviolet light.
• Polypropylene (PP) is a popular material used in applications which are exposed resistance to ultraviolet light and other relevant, environments. 

In the selection process of plastic regulators it is important to carefully analyse methods, connections and specifications which can deliver premium performance. Some of the features that should be taken into consideration are dimension, resistance against pressure, temperature, stress, friction etc.

 

Majority of the times the key features are engraved on the surface of the product by manufacturers of valves. Some plastic valves however are activated manually; electric or sometimes even are automated. Plastic valves are used slurries, compressors air, tanks which contain fuel like gasoline, liquefied petroleum gas etc. Plastic regulator manufacturers are undergoing tremendous design challenges, due to the abundance of various external factors such as sensitivity to temperature and thermal expansion and contraction. However engineers are working on creating innovative and durable cost-effective solutions of valves ideal for metallic as well as plastic fitting systems.
