Globe Valves
Bellows seal globe valve
A bellows seal addresses leakage along the moving stem. Seat shutoff is a different sealing function. Specify bellows material and service cycles, any backup packing, and separate external-leakage and seat-test requirements.
About the bellows seal globe valve manufacturerThese are family-level options. Confirm the offered series rating and materials against its approved datasheet.
Bellows sealing is an external-leakage control feature, not an unconditional zero-leakage guarantee. Agree the test method, acceptance limit, pressure, temperature and operating cycles for the offered valve before approval.
SERIES SELECTION
Does a bellows seal define the globe valve's seat leakage?
No. A bellows seal concerns external stem sealing; seat-shutoff acceptance must be specified separately for a bellows seal globe valve. Confirm bellows material, construction, approved service and cycle limits, and any secondary packing or monitoring provisions. Agree external-leakage and seat tests independently instead of assuming unconditional zero leakage or unlimited cycling.
