Globe valves / LIANGGU
Cryogenic Extended Bonnet Globe Valve
This model is a globe valve distinguished by an extended bonnet and controlled stem sealing arrangement designed for low-temperature service. For a project quotation, share the required size, pressure designation, materials, seating, connections and quantity. Final suitability is confirmed against the approved specification.
PRODUCT DETAILS
Understand this valve.
Working principle
a linear stem moves a guided disc or plug toward a stationary seat; the tortuous flow path creates more pressure loss than a gate valve but supports controlled shutoff and, with suitable trim, limited regulation; verify bonnet extension and flow direction
Typical applications
cryogenic storage, LNG vaporization systems, liquid gas transfer, and cold-box auxiliaries
Selection priorities
minimum temperature, bonnet extension, flow direction, cavity behavior, packing location, and low-temperature test scope
