Edwards SP40KN Speedivalve, KF40, manual operation, Nitrile diaphragm, aluminum alloy, C33405000.
These NEW Edwards SP40KN Seedivalve come with Nitrile 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 are suitable for pipeline mounting only.
