The 2-9KG CO2 Extinguisher Valve (Model 2005) is a manual, lever-operated cylinder valve for CO2 extinguisher applications. The lever mechanism is used to actuate the valve, while the threaded interfaces connect the valve to the cylinder and the discharge assembly. The dip-tube connection accommodates the corresponding dip tube where required by the extinguisher design.
A burst-disc safety device is specified at 200±15 bar.
For OEM or ODM projects, please provide a technical drawing or sample, cylinder neck details, outlet connection requirements, dip-tube dimensions, intended market, and required approvals. Custom options should be confirmed in writing against the final approved drawing and specification.

To support dependable product quality, buyers should request model-specific documentation covering the materials, critical dimensions, thread gauges, sealing interfaces, assembly controls, and inspection criteria. Relevant checks may include dimensional verification, valve operation checks, leakage testing, and verification of the safety device against the approved specification.
This valve is intended for integration into compatible CO2 fire extinguisher assemblies. The suitability of a finished extinguisher for electrical equipment areas, industrial facilities, marine environments or other applications depends on the complete extinguisher's design, approval, capacity, and local fire-safety rules. Confirm the end-use requirements before selecting the valve.
Installation, charging, pressure testing, and servicing must be carried out by qualified personnel following the extinguisher and cylinder manufacturer's approved procedures. Before assembly, verify the cylinder-neck thread, outlet connection, dip-tube thread, sealing method, torque requirements, and approved safety-device specification. Never rely on thread names alone where standards or tolerances may differ.
l Inspect for visible damage, corrosion, deformation, or contamination.
l Check the lever mechanism and threaded interfaces according to the approved inspection procedure.
l Perform leakage and functional tests using qualified procedures and suitable equipment.
l Replace damaged or activated safety components only with approved parts.
l Follow applicable local regulations and the extinguisher manufacturer's service schedule.
Model 2005.
