Globe valves / LIANGGU
Forged Steel Globe Valve
This model is a globe valve distinguished by a compact forged pressure boundary suited to smaller high-integrity lines. 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 joint and end preparation
Typical applications
refinery drains, vents, bypasses, steam services, and high-pressure instrument connections
Selection priorities
bore, bonnet joint, end preparation, packing, required NDE documentation, and forging grade
