Saunders A Type & KB Type

## Diaphragm Valves

Fluidcare supplies the complete Saunders® diaphragm valve range — the original diaphragm valve design invented by P.K. Saunders in 1928. Available in A Type (weir) for on/off and throttling service, and KB Type (straight-through) for full bore applications with minimal pressure drop.

Diaphragm valves are uniquely suited to applications involving abrasive slurries, corrosive media, viscous fluids and aseptic / pharmaceutical processes. The diaphragm isolates the process fluid from the actuating mechanism, eliminating the risk of contamination.

- Saunders A Type — weir body for optimum shutoff
- KB Type — full bore straight-through for low pressure drop
- Diaphragm isolates media — no contamination risk
- No packing or stem seal — zero external leakage
- Elastomeric and PTFE diaphragm options
- FDA, USP Class VI, 3A certified for pharma/food
