Hand operated diaphragm valve designed specifically for 3A / FDA compliant bioprocessing tasks. The forged 316L stainless steel body can be delivered with your specific surface finish with a range of diaphragm materials to suit positive control of ultra-pure, abrasive and aggressive fluids. The diaphragm type valve is preferred in these applications due to its favorable flow characteristics, its cleanability and its zero dead volume design.
