Flow Limit + Strainer Cartridge 0.17 Lt/s ID

Cartridge for installation into AFL Valves. All sizes of AFL Valve use the same size Cartridge. There are several Cartridges available: Automatic Flow Limiting, Auto Flow Limiting & Strainer, Strainer only. All Cartridges have identical external dimensions and incorporate a stainless steel Cross Pin, which enables easy extraction with long nose pliers. Where space prohibits pliers, a wire hook can be used instead. There is no Circlip required because the "on" position prevents the Cartridge moving. AFL CArtridges limit the flow by automatically varying the size of the orifice of the Cartridge. As the flow approaches the specified rate, the orifice contracts like a camera lens. The regular flexing tof the cartridge material avoids build-up of scale and allows small particles to pass through. The properties have been tested over 20 years and are stable up to 65 C. Valves should be installed, the system flushed and chlorinated before Cartridges are fitted. Cartridges can be installed with system fully pressurised.
