Manual Bellows Sealed SS Inline Valves (KF & ISO flanged), The moderate conductance of inline valves results from the gas flow making two right-angle turns through the valve.
NOTE: We check each valve with a helium mass spectrometer with a sensitivity of 2 x 10-10 std. cc/sec. before shipment. Pneumatic valves require a solenoid operator (sold separately). Please see the Inline Valve Accessories chart for the sizes/voltages that are available.
