Ceramic vs solenoid valves

August 2020 Valves, Actuators & Pump Control

Selecting the right valve goes beyond just understanding the application it needs to serve. It is also important to factor in cost efficiency, durability and maintenance considerations. In some cases, according to Lionel Maasdorp, MD at Allmech, switching from a solenoid valve to a ceramic ball valve can help to cut down on costs, while improving performance.

“Various industries, including water treatment and agriculture, make use of ceramic ball valves for a multitude of applications, usually where the demands on the valve exceed the capacity of conventional valve materials,” says Maasdorp. “The high-performance nature of ceramic valves means they often have a greater tolerance for wear, corrosion, and high temperatures than many other types of valves. However, even within the category of ball valves, there are different types available for specific purposes.”

For this reason, many Allmech clients are choosing to switch to ceramic ball valves from solenoid valves where possible. While the diaphragm in a solenoid valve may collect dirt as liquid moves through it, ceramic ball valves do not have a diaphragm, meaning they are less prone to dirt build-up inside the valve.

Furthermore, in sensitive environments or where minimal wastage is an important operational requirement, ceramic ball valves can provide a better option as the design of the valve means the ball core and seat are precisely ground in a pair to ensure there is no leakage. In contrast, solenoid valves are prone to seepage and blockages and need to be closely managed for leaks.

Maasdorp says that ceramic ball valves are ideal for many water-related applications, including water saving systems, industrial automatic control systems, automatic small application sewage systems, environmental protection projects, water supply and drainage, food and water treatment, and irrigation systems.

The ceramic ball valve also has the advantage of small flow resistance, good corrosion resistance, good wear resistance and long lifetime, making it an excellent option for inclusion in an industrial system.

“Ceramic ball valves have many important factors that make them an excellent choice for robust applications,” concludes Maasdorp. “They are cost effective, low maintenance, durable and their self-balancing design lowers torque and makes for smoother operation.”
