For high-quality and durable performance, PVDF (Poly Vinyl Deformable Plastic Film) or PVC vinyl (PVC) valves are the ones you need. These valves have the properties to withstand extreme working conditions like chemical reflux, high temperature, and hydrostatic pressure. They are also highly resistant to erosion, corrosion, and stress cracking. They are designed for flexibility and low maintenance so you can save money and time. They are ideal for applications where the valve is not readily accessible. And because they come in a variety of materials, they can easily be customized for specific applications and unique design features.
There are many advantages to using pvdf valves in chemical resistance. The valve body is made of plastic, metal, or another material with an electrochemical or mechanical function. Some examples are valve bodies made of stainless steel, aluminum, copper, titanium, brass, and stainless steel alloys. And because the valve is in contact with chemicals for extended periods of time, its design needs to be chemically resistant, which can range from electrostatically resistant to mechanically resistant.
One of the most common uses for pvdf valves is as a chemical valve in the production of sulfuric acid. The production of sulfuric acid involves the use of numerous intermediates, including sulfuric acid, which is one of the main ingredients of gasoline, among others. To keep these intermediates from coming into contact with other chemicals, an expensive and hazardous chemical called trihalomethane (THM) must be used. But a PVDF valve can prevent the chemical from coming into contact with the valves or their components.
Another common use of pvdf valves is as an abrasion resistance in the beverage processing industries. It is important that the products of the beverage processing industry do not contain petroleum, which has high surface tension and poor abrasion resistance properties. In order to meet this requirement, manufacturers often use PVC instead of other metals, which reduce the chances of the metal binding to the product. As such, PVC is a superior thermal conductor and allows the products to stand up to high temperatures and abrasion.
PVDF is also a popular option for valves in the food and beverage processing industries. The PVC material is extremely lightweight and can easily conform to product size requirements, making it an excellent choice for industrial applications where size is an issue. Additionally, PVC is easy to clean and provides excellent chemical resistance properties.
PVDF valves are also ideal as temperature and pH controllers for various applications. In the case of temperature control, it is important that the valves can maintain a constant temperature across the entire range of temperatures. As such, the valve is typically connected to a thermometer to ensure that valves maintain the right temperature throughout the manufacturing process.
