Common specifications

Key specifications

Dixon's catalogue prints the 1/2 in valve as 12 mm (part VC-4B-015); this page follows the store size of 15 mm. Dixon also lists a 100 mm (4 in) valve, VC-4B-100, which is not part of this listing.

Selecting the right option

Choose the size from the female BSP thread on your pipework. A swing check valve passes flow in one direction only, so fit it with the flow direction in mind and keep it away from points where flow pulses hard. For a spring-loaded in-line check valve that Dixon lists for vertical, horizontal or oblique positions, see the brass in-line range: Dixon Brass Inline Spring Check Valve Europa Brass Stem.
