1077981 – Spring, Compression, SS, 5524

The AqMatic 1077981 is a stainless steel compression spring designed for 5524-series diaphragm valve assemblies, used in water treatment, filtration, and industrial control systems.

This spring is a critical internal component that provides the force required for valve positioning, return action, or fail-safe operation depending on the valve configuration. In 5524 isolated bonnet valves, compression springs are used to maintain consistent diaphragm movement and ensure reliable opening or closing under varying pressure conditions.

Constructed from stainless steel, this spring is built to handle repeated cycling, resist corrosion, and maintain performance in wet or chemically active environments. It is typically replaced during valve rebuilds when spring fatigue or loss of tension begins to affect valve timing, sealing, or responsiveness.

This part is used within assemblies that may include diaphragm components, plates, and other internal hardware, and is commonly serviced alongside those parts in maintenance cycles. It is often found in systems that also utilize V42 diaphragm valves, K53 series valves, and control systems driven by stagers.
