Pneumatic Bellows Sealed Copper Bonnet Gate Valves (CF Flanged)

Gate Valves handle applications in semiconductor, R&D and industrial processes. They are most often used to isolate pumps and sample entry locks from HV or UHV work chambers.

Features

CF Flanged (with Copper Gasket): Operate in the atmosphere to 10^-11 torr pressure range, bakeable up to 200°C (with actuator removed)
General purpose polished Stainless Steel
Provide high conductance within a compact design
100,000-cycle service before requiring maintenance
Pneumatic valves close or remain closed in the event of power loss or loss of air pressure
All Pneumatic 2.75" flange O.D. and larger models incorporate magnetic REED switches for position indication (micro-switch optional)

Note

For ease of maintenance, the carriage assembly can be removed from the body without requiring removal of the valve from the system. Please contact us for options such as roughing ports or valves that remain open in the event of power failure.
Please contact us for options such as roughing ports or valves that remain open in the event of power failure.
