520-T – Retainer, Spring, 520

The 520-T retainer spring is a replacement spring component used in AqMatic and AquaMatic 520 valve assemblies. This part is designed to maintain proper internal component positioning and support reliable valve operation during normal cycling and service conditions.

Used in maintenance and rebuild applications, the 520-T spring is commonly installed during valve servicing when worn or fatigued internal hardware is being replaced. Maintaining proper spring tension and alignment helps support consistent valve performance and long-term reliability in filtration, water treatment, and industrial process systems.

This component is available within the AqMatic parts and accessories collection and may be used alongside other replacement diaphragms, retainers, shafts, and internal rebuild components for compatible valve assemblies.
