Globe valves / LIANGGU
Oxygen Service Globe Valve
This model is a globe valve distinguished by oxygen-compatible material selection and controlled cleanliness for ignition-risk management. 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 cleaning standard and lubricant restriction
Typical applications
industrial oxygen distribution, air-separation units, oxygen skids, and clean gas isolation
Selection priorities
oxygen concentration, cleaning standard, lubricant restriction, velocity limit, trim material, and packaging cleanliness
