Clifford Springs: Spring Material Selection in Valves and Actuators

In this article, Clifford Springs explains more about the critical role of spring material selection in valves and actuators.

The functionality and efficiency of valves and actuators used in various industries depend heavily on an often-overlooked component: springs.

These vital springs ensure controlled and precise movement in both the opening and closing mechanisms of valves and actuators, so that the required pressure and flow of fluids is maintained within the systems.

To optimise functionality and longevity, therefore, selecting the appropriate spring material and design is essential.

Different industries and environments have unique requirements for their springs as temperature, pressure, and corrosion resistance will all differ. These elements need to be taken into account when designing the spring and selecting the right material.

Some examples of this include:

1. Oil & Gas Industry

Springs in the oil & gas sector must be able to withstand extreme temperatures, high pressures, and corrosive environments. Materials such as Inconel and Hastelloy offer excellent corrosion resistance, high-temperature stability, and strength. These alloys ensure that springs maintain their mechanical properties, leading to reliable performance in demanding conditions.

2. Chemical Industry

In this sector, springs can be exposed to aggressive chemicals, necessitating a high degree of chemical resistance. Stainless steel 316 is a common choice in these situations, but more advanced alloys, such as Monel, can provide the required resilience and durability.

3. Food and Beverage Industry

Hygienic and contamination-free processing is a top priority in the food and beverage industry. Springs must be made from materials resistant to corrosion, wear, and microbial growth. Stainless steel 316 and PEEK are popular choices due to their excellent corrosion resistance and compliance with stringent hygiene standards.

The importance of springs in the valve and actuator world should not be underestimated, nor should the diverse requirements of different industries. A one size fits all approach to spring materials cannot be followed given the diverse requirements.

Clifford Springs understands this and is here to help engineers across different industries. When we understand more about what you want to achieve, we can help you identify the spring materials that will have a positive impact on the performance and lifespan of your valves and actuators.
