520-KB – Guide, Housing, 520

The 520-KB guide housing is a replacement component used in AqMatic and AquaMatic 520 valve assemblies. This part supports internal valve component alignment and positioning within the valve assembly during operation and cycling.

Guide housing components are commonly replaced during valve rebuild and maintenance procedures when internal wear, corrosion, or component damage affects valve performance or assembly stability. The 520-KB housing is used in compatible 520 valve configurations operating in water treatment, filtration, and industrial process control systems.

This replacement component is part of the broader AqMatic Parts & Accessories collection and may be installed alongside related diaphragms, shafts, springs, retainers, and rebuild hardware used in routine valve servicing. Additional product and system information is available within the V42 documentation library and compatible valve series resources.
