Advantages of Using a Plastic Valve
Plastic valves are an excellent choice for applications where corrosion and corrosive buildup are a major issue. Unlike metal, plastic piping remains smooth and free from buildup even after years of use. They also resist airborne corrosives, eliminating the need for costly coatings. Polyvinyls are also non-leaching, making them easy to install and maintain. These properties make them the preferred choice for many industrial applications.
Thermoplastics, which are derived from the chemical industry, exhibit excellent corrosion resistance. This makes plastic valves an ideal solution for many applications that require corrosive chemicals. Compared to metals and metal alloys, plastic valves are also cheaper. They are also much lighter than their metallic counterparts, facilitating installation, transport, and storage. This lowers logistics and accident risks. Thermoplastics are also suitable for harsh environments.
Plastic valves can handle high temperatures, low thermal conductivity, and corrosive chemicals. Most of them feature a coil encapsulation technique, which separates the coil winding from the rest of the valve. Moreover, they are UL-listed and receive hazardous location ratings. The encapsulated type coils are made from high-end engineering grade polymer polyamide. This tough material is glass reinforced and exhibits good chemical resistance. The encapsulated type of coils can operate in an ambient temperature of 135 degrees.
Due to the high temperature and pressure limitations of plastic valves, they are only suitable for some industries. In some cases, a plastic valve cannot be used in extremely high temperatures. This is why a metal valve is the best option for such applications. Fortunately, many manufacturers have adapted this material to suit various requirements. This versatility allows for a wide range of uses, which means that plastic valves can be the most versatile choice for your fluid and corrosive applications.
The most important benefits of plastic valves are the lower cost and higher temperature ratings than metal valves. They are suitable for applications requiring high temperature and corrosion resistance. Despite their low weight, plastic valves can perform better than metal valves. Further, they are lighter and easier to handle. This allows for easier handling. They can be transported in large quantities and are far less expensive than their metal counterparts. They are also more resistant to UV rays and weathering.
As plastics are highly resistant to chemicals and corrosion, plastic valves are an excellent choice for a variety of applications. They are durable, able to withstand a variety of pressures and temperatures and are often rated for use in hazardous locations. This allows them to be used in applications where high temperatures are required. They are also affordable and flexible compared to their metallic counterparts. In addition, they can be used in exposed settings.
The plastic valve industry has been around for more than fifty years. While it is an emerging industry, it has carved out a niche for itself. Engineered plastic valves will continue to make inroads into the high purity and corrosive liquid markets.
