Stainless Steel Solenoid Valves for Pharma and Chemical Industries




In addition to using hazardous chemicals in its products, the pharmaceutical industry uses very high temperatures for its cleaning processes, and the media it uses for these clean-downs can be extremely corrosive. Different fluids are handled in chemical processing plants, but they are equally challenging. Solenoids are an ideal solution for fluid control in industries such as these, where accuracy and speed are crucial. It is critical to use a specially developed solenoid valve for chemical applications such as these to ensure that the valve works appropriately and is not compromised by the environment in which it operates. Here's why stainless steel solenoid valves are a great choice for chemical and pharmaceutical manufacturing.

How does stainless steel use benefit solenoid valves?

Media handling with stainless steel is popular in the pharmaceutical industry because it is durable, can withstand exposure to many of the chemicals used to sanitize pharmaceutical products, and has a high tolerance for heat-based sanitation methods like steam-in-place (SIP).

Grade 304 stainless steel is a common variant and is often used for its high resistance to chemical corrosion thanks to nickel additions. Because of its ability to resist oxidation and how easily it can be cleaned and sterilized, surgical stainless steel is often called "surgical steel."

In cookware, grade 316 stainless steel is often used. Generally, it is used for materials handling applications involving corrosive chemicals or saline solutions. It is also useful for extremely high-temperature sanitation processes, as its maximum continuous use temperature is around 800°C. The 316 grade of stainless steel contains both nickel and molybdenum, making it more resistant to chlorides.

Therefore, stainless steel-bodied solenoid valves are ideal for use with hot temperatures and aggressive media, such as those encountered in chemical processing.

Choosing stainless steel solenoid valves: what to look for

Aira Euro Automation has been supplying solenoid valves for many years, including stainless steel solenoid valves. The following are a few things to consider when selecting a solenoid valve option.

For chemical applications, solenoid valves may be approved with specific approvals, such as ATEX EEx d IIC T6, which means they can be used in hazardous areas. 

In comparison to the engineering plastic solenoid valve types we supply, which are also suited to aggressive media, stainless steel solenoid valves are more durable and can withstand much higher temperatures, making them suitable for cleaning processes at higher temperatures – and, in some cases, for corrosive media as well, though it depends on the other components of the solenoid valve and what it is intended to do.

You've come to the right place if you're looking for stainless steel solenoid valves for chemical applications. With technical expertise in control and instrumentation, we can offer guidance and advice on selecting the appropriate solenoid valve type to meet your particular requirements, and we'd be happy to discuss solenoid valve applications with you and which configuration would be most effective.

Aira Euro Automation is a leading Industrial valve manufacturer in Zambia. We have a wide range of industrial valves.
