32mm (1 1/4" BSP) Nylon Spring Loaded Check Valve Female Irrigation
The Anka plastic check valves minimise the development of reverse flow that may damage pumps.
It restricts flow to only one direction (spring return to close).
It has a compact and robust plastic design and is useful where a height differential exists between the pump and the water source.
It is an inexpensive way to make sure that a single centrifugal pump is primed every time it cycles and can be installed in any orientation, but direction of flow is specific.
If it is installed with a filter screen it can be used as a foot valve.
