These NEW Edwards SP16K Seedivalve come with Viton diaphragm and the valve bodies are made of aluminum alloy. The complete valve is leak tight to better than 10-6 mbar l s-1 / 7.5 x 10-7 Torr l s-1 at 1 bar differential. The mechanism is isolated from the system by the diaphragm resulting in an extremely rugged and "dirty" system tolerant valve. Diaphragm is Viton fluoroelastomer. Valves can be panel mounted. These valves have red indicators to show the "open" position. Body: Aluminum alloy to BS1490 Handwheel and bonnet: Glass reinforced plastics Diaphragm: Viton fluoroelastomer Maximum leak rate across body: 10-6 mbar l s-1 / 7.5 x 10-7 Torr l s-1
