What does Clack valve mean in practice?
Clack valves come in many versions of bodies, drivers and pistons, so the brand itself does not determine the function of the device.
When does it matter?
Parts, programs and seal kits must match the exact model and filtration or softening application.
Which solutions are related to it?
The model is identified from the plate and configuration, and service is performed with the correct piston, spacers, injector and flow restrictor.
