VALVE MATRIX
BY : Rory Macnamara
Valves are known by different names and can be a cause of confusion .
Nonetheless , we provide the matrix as a reference to the names and applicable National Standards ( SANS ). Manufacturers have provided and confirmed the information . For ease of reference each manufacturer is colour-coded by name and cross .
It must be noted that all information was supplied by the manufacturer / distributor and is published in good faith . Refer our disclaimer . Please note all componentry must comply with the standard requirements .
End users / specifiers still retain responsibility for checking the SABS Mark certificate and the supporting documents that are an integral part of the certificate .
Where there is no SANS designation , we still list the four valves on the matrix .
