Gate Valves
Cryogenic or extended-bonnet gate valve
An extended bonnet is one part of a low-temperature gate valve specification. The extension, materials, stem sealing and required cold tests must be reviewed together for the stated minimum temperature and installation orientation.
About the cryogenic or extended-bonnet gate valve manufacturerThese are family-level options. Confirm the offered series rating and materials against its approved datasheet.
SERIES SELECTION
What must a cryogenic gate valve quotation define?
Define the fluid phase, minimum and operating temperatures, pressure, orientation and insulation boundary for a cryogenic or extended-bonnet gate valve quotation. Request the extension drawing, suitable materials and model-specific low-temperature test scope for approval. An extension or a general material name does not establish the cold qualification of the offered configuration.
