The ANKE 2-6 CO2 Fire Extinguisher Valve is a lever-operated cylinder-head valve designed to control the retention and manual release of carbon dioxide from a compatible extinguisher cylinder. As a pressure-bearing component, the valve must be matched to the cylinder neck, discharge assembly, operating pressure, and applicable regulatory requirements before installation or use.
The reference product description specifies a brass body, with HPb59-1 or an equivalent alloy identified as the material option. The described manufacturing sequence includes forging, precision machining, grinding, polishing, surface plating, assembly, and functional inspection. Chrome plating or nickel plating may be specified according to project requirements.The 2-6 CO2 Fire Extinguisher Valve describes a burst-disc safety device with a nominal setting of 200 ± 15 bar, PZ27.8 inlet thread, W21.8-14 outlet thread, and M10×1 dip-tube connection.

The 2-6 CO2 Fire Extinguisher Valve uses brass for its machinability and suitability for precision threads and sealing surfaces. The final alloy designation and material traceability should be stated in the order documentation where required.
● Forging of the valve-body blank
● Precision machining of threads, sealing surfaces, and internal passages
● Grinding and polishing to achieve the specified surface finish
● Chrome or nickel plating when included in the approved specification
● Assembly and functional testing of the valve and safety device
The reference document describes batch dimensional inspection, functional checks, verification of the burst-disc activation pressure, and leak testing at relevant sealing interfaces. Inspection methods and acceptance criteria for the 2–6 kg configuration should be agreed and documented before production.
The 2-6 CO2 Fire Extinguisher Valve have CE, TÜV, and ISO 9001 certifications.
When incorporated into a compatible and properly certified CO2 extinguisher, this type of valve may be used in commercial, industrial, electrical-equipment, laboratory, or marine settings where CO2 extinguishers are specified. Suitability depends on the complete extinguisher design, the fire risks present, and local regulations.
Installation should be performed by qualified personnel using the approved cylinder and valve specifications. Confirm the inlet and outlet threads, sealing method, dip-tube connection, torque requirements, pressure rating, and safety-device setting before assembly. Never force mismatched threads or substitute an unapproved safety device.
● Inspect the valve body for corrosion, impact damage, or other visible defects.
● Check the lever mechanism for damage and appropriate movement.
● Inspect the safety device for obstruction, corrosion, deformation, or signs of activation.
● Have leakage checks and servicing performed by qualified personnel according to the extinguisher manufacturer’s instructions and local requirements.
● Replace activated or damaged safety components only with approved parts and settings.
A1: This 2-6 CO2 Fire Extinguisher Valve for a 2–6 kg CO2 fire extinguisher. Compatibility with a specific cylinder must be confirmed by the manufacturer.
A2: The describes a brass body and chrome-plated or nickel-plated finishes. Confirm the alloy and finish for the selected model.
A3: The source document lists PZ27.8 inlet, W21.8-14 outlet, and M10×1 dip-tube threads. These values must be verified for the 2–6 kg configuration before ordering.
A4: The a burst-disc setting of 200 ± 15 bar. The appropriate setting must be validated against the cylinder design and applicable standards.
A5: yes, plating type and handle color/style. Other changes, including threads, dip-tube connection, or safety-device setting, require technical review and written approval.
A6: Request the current technical datasheet and drawing, material details, applicable test reports, and valid certificates covering the exact model.
● Confirm the valve is specifically rated and approved for the intended 2–6 kg cylinder.
● Approve the drawing, thread standards, material grade, surface finish, and valve weight.
● Verify the burst-disc setting and working/test pressure against the cylinder specification.
● Check current certificates and their scope before making compliance claims.
● Agree inspection, packaging, MOQ, lead time, payment, and shipping terms directly with the supplier.
