These medium Ideal Vacuum Super-Seal pneumatic bellows 90° angle valves have 2-1/2" OD weldable tube inlet and outlet ports, making them perfect for customizing with different types of inlet and outlet port flanges. They are designed primarily for use in the 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 Viton bellows seat O-ring seals. Super-Seal valves are bakeable up to 100°C (valve body only). These valves can be mounted in any orientation. These medium-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.

These medium Ideal Vacuum Super-Seal pneumatic bellows 90° angle valves have 3" OD weldable tube inlet and outlet ports, making them perfect for customizing with different types of inlet and outlet port flanges.
