Spring-Check Foot Valves Plain

Description

Spring-check foot valves are one-way non-return valves that are generally installed at end-of-line or pump inlet pipework. These PVC valves with stainless steel spring have excellent corrosion-resistant characteristics and can be dismantled for maintenance and inspection purposes.

Sizing - Solvent Weld Pipe & Fittings

Imperial (inch) PVC pipe and fittings sizing is not straightforward. They are sized by their nominal bore or approximate inside diameter.

The following table details pipe outside diameters (o.d.) for each imperial size.  The inside diameter (i.d.) of the socket end of the corresponding fitting will be the same as the outside diameter of the pipe.
