The AqMatic 43081 is an upper diaphragm plate for 5521-series diaphragm valve assemblies, used in water treatment, filtration, and industrial flow control systems. It is a direct replacement for part 1075022, designed to restore proper diaphragm alignment and valve performance.
This component sits above the diaphragm within the valve assembly, working in conjunction with the lower plate to maintain correct diaphragm shape, lift, and sealing response during operation. In 5521 isolated bonnet valve designs, the upper and lower plates act together to distribute force evenly across the diaphragm, ensuring consistent actuation and reliable shutoff.
Because diaphragm plates are matched to specific valve geometries, this part must be used with the correct 5521 configuration. It is typically replaced during rebuilds when wear, deformation, or corrosion begins to affect diaphragm movement or sealing performance.
This part is commonly serviced alongside diaphragm kits and internal components in systems that may also include V42 diaphragm valves, K53 series valves, and control systems using stagers.
