The 428-SC Spring Assist Close Repair Kit is an internal parts kit designed to restore the spring assist close functionality of AqMatic 428 series diaphragm valve assemblies. This kit includes the core internal components required to maintain proper mechanical closing force, helping ensure the valve returns to a fully closed position during operation.
Within the valve assembly, the spring assist close components apply force above the diaphragm, supporting reliable shutoff even when line or control pressure is reduced. Over time, these internal parts can wear or lose effectiveness, leading to inconsistent sealing or delayed closure. Replacing them with the 428-SC repair kit helps restore proper valve performance and maintain dependable operation in water treatment, filtration, and industrial fluid control systems.
Designed specifically for AqMatic 428 series valves, this repair kit is commonly used during routine maintenance and rebuilds where restoring consistent shutoff and extending valve service life are essential.
