·        High pressure

In this article, we will learn about how to select the right valve brand for your requirements by exploring their

·        Features

·        Benefits

·        Applications

What are PFA-lined valves?

PFA (Perfluoroalkoxy alkane) is a high-performance fluoropolymer. It can handle harsh chemicals. It also offers high thermal stability and low friction properties. To prepare valves for challenging conditions, they are given an internal lining of PFA. This PFA lining doesn't let aggressive media come in contact with the valve's metal body. The most common types of PFA-lined valves include:

·        Ball valves

·        Butterfly valves

·        Diaphragm valves

·        Plug valves

Each of these valves is designed for specific applications, offering unique benefits.

Why go for PFA-lined valves?

  • Exceptional Chemical Resistance: A PFA lining can handle a wide range of chemicals, including:
    • Strong acids
    • Bases
    • Solvents
    • Oxidizers

This not only protects the body of the valve but also keeps the valve durable and low maintenance.

  • High thermal stability: A valve with a PFA lining can withstand temperatures between -200°C and 260°C. This high thermal stability makes it ideal for applications that exude extreme temperatures.
  • Leak-proof: When the PFA lining separates the valve material from the media, it ensures no leakage of corrosive substances. This helps in ensuring a safe and efficient operation.
  • Smooth surface finish: Since PFA is a non-stick and smooth surface, it doesn't allow any accumulation of deposits. This ensures a consistent flow rate minus heavy clogging.
  • Added strength: Most modern-day valves are made of sturdy metals and alloys. The PFA lining adds an extra layer of strength. This gives the valve the ability to perform under high-pressure conditions. In the long run, the PFA lining increases the valve's lifespan.
  • Cost-effectiveness: The purchase cost of a PFA-lined valve may be higher; however, over a period of time, it result in substantial cost savings due to factors such as:
    • Consistent flow rate
    • Less maintenance
    • Durability
  • PFA-lined valves are safe: By preventing the leakage of hazardous chemicals, PFA-lined valves contribute to safer working environments.

Which industries use PFA valves?

  • Chemical industry: Chemical industries must handle aggressive chemicals in several processes. PFA-lined valves help in doing just that.
  • Pharma industry: Maintaining the purity of processes is critical in the pharma industry. PFA-lined valves reduce the risk of contamination. They are suitable for handling sensitive chemicals.
  • Food and Beverage: The reduced risk of contamination also makes PFA-lined valves ideal for the food industry.
  • Oil & Gas: The capability to handle aggressive fluids such as crude oil makes PFA-lined valves perfect for the oil & gas industry.

How to select the right PFA-lined valve?

It is important to check the compatibility of the PFA lining with the chemicals and media you need to handle. The PFA-lined valves should also be able to work at the required temperature range and pressures. The valve should also be of the correct size. It is also important to consider the initial cost and the lifecycle cost of the valve. It is essential that you do not get overwhelmed with the number of brands offering valves. Once all the other criteria are checked, you should look at the brand offering the PFA lined valves. Check its customer stories and read about its history before making a decision.

What is negative suction in a pump?

  What is negative suction in a pump? Negative suction in a pump refers to the scenario where the pump is drawing liquid up from below its centerline. We measure the space between the pump's centre and the liquid's surface in "head feet." It can be a negative value (below the pump) or a positive value (above the pump). In simpler terms, a negative suction head occurs when the surface of the fluid is below the level of the pumping unit. This is also referred to as a suction lift. The significance of negative suction in a pump lies in its impact on the pump's operation and efficiency. If not properly managed, negative suction can lead to issues such as cavitation, which is a common cause of pump failure. Cavitation occurs when there are changes in pressure within the pump, leading to the formation of vapour bubbles that can cause damage when they collapse. Therefore, understanding and managing negative suction is crucial for maintaining the efficiency and long...
