Ideal Vacuum Large Super-Seal Conflat CF 8.0 in. UHV Pneumatic Bellows Right Angle Valve, Rotatable Flanges, Copper Bonnet Seal, Double-Acting

Out of Stock

These large Ideal Vacuum Super-Seal pneumatic bellows 90° angle valves have CF 8.0" inlet and outlet ports with rotatable flanges. They are designed primarily for use in the ultra high-vacuum range (10 Torr), with leak rates of 10 Torr l/s (He) but can be used up to positive pressures of 60-80 psi. These valves are constructed of a 304L stainless steel valve body and mechanism, an aluminum actuator, and have copper bonnet seals. Super-Seal valves are bakeable up to 100°C (valve body only). These valves can be mounted in any orientation. These large-sized Super-Seal valves require air to both open and to close. They do not have a spring return and therefore do not automatically close. Low volume, dry, compressed air in the range of 60-to-80 psi is needed. Because they do not have automatic spring closure, they cannot provide failure protection to preserve chamber vacuum in case of loss of power or air supply.
