compressed air valve / aluminum / vacuum / normally closed
for compressed air
normally closed, electromagnetic, compact
The agilent direct-acting electromagnetic block valves gets rid of the necessity for compressed air in several vacuum devices. The valves that are normally closed are small and require very little maintenance; plus, they last for 250 000 cycles. EMBVs are offered with NW16 or NW25 connecting flanges, and come with either aluminum or nickel-plated exteriors for somewhat corrosive uses. Also, if several different voltages are needed, those options can be added.
