The CO₂ Fire Extinguisher Valve for 2–3 kg is intended to serve as the control valve for a 2–3 kg CO₂ fire extinguisher. The valve provides the interface between the cylinder, discharge assembly and dip tube while allowing the operator to initiate and stop discharge through the manual handle mechanism.
The squeeze-grip operating arrangement is configured for direct manual operation. The valve architecture also incorporates a dedicated safety device intended to provide over-pressure protection. The specified safety-device setting for this model is 200 ±15 bar.

Important: The thread and safety-device values above are transcribed from the supplied CO₂ Fire Extinguisher Valve for 2–3 kg product image. They should be treated as the controlling product-information values for this revision, subject to confirmation against the approved technical drawing and inspection documentation.
The supplied reference document describes the valve family as using a forged copper-alloy valve body. For CO₂ Fire Extinguisher Valve for 2–3 kg, the final alloy designation, forging condition and dimensional tolerances should be controlled by the approved production drawing and material specification rather than inferred from appearance.
The squeeze-grip handle provides a practical manual interface for valve actuation. The final handle force, travel, spring characteristics and internal sealing arrangement should be validated through the approved design and production inspection procedure.
The CO₂ Fire Extinguisher Valve for 2–3 kg configuration uses PZ27.8 at the inlet, W21.8-14 at the outlet and M10×1 for the dip-tube connection. Thread engagement, sealing method and mating components should be checked against the corresponding cylinder, hose/horn and dip-tube specifications before assembly.
This valve is intended for CO₂ fire extinguisher assemblies in the 2–3 kg nominal filling range. CO₂ extinguishers are commonly selected for applications where a clean gaseous extinguishing medium is required, including certain electrical and equipment-protection environments. Suitability for a particular installation depends on the complete extinguisher system, fire risk, local regulations and the extinguisher manufacturer's approved design.
● Do not use the valve outside its approved pressure, temperature, cylinder and media specifications.
● Do not change the safety-device setting without qualified engineering review and approval.
● Verify thread compatibility before assembly; thread appearance alone is not sufficient for interchangeability.
● Pressure testing and leakage testing should be performed according to the approved manufacturing and inspection procedure.
● Final installation and servicing should be carried out by qualified personnel in accordance with applicable requirements.
A professional product page should make the evidence behind technical claims clear. For this valve, the recommended quality-control sequence includes:
1. Incoming material inspection against the approved material specification.
2. Dimensional inspection of PZ27.8, W21.8-14 and M10×1 interfaces and other critical dimensions.
3. Inspection of sealing surfaces, safety-device interface and operating mechanism.
4. Pressure and leakage testing according to the approved test procedure.
5. Final inspection of appearance, marking, configuration and packaging.
6. Retention of inspection records and traceability information where required by the customer or applicable system.
7. Third-party inspection can be arranged when required by the project.
Ningbo Kaituo Valve Co., Ltd., under the ANKE brand, is described in the supplied reference material as a manufacturer and supplier of fire extinguisher valves and related components. The reference document states that the company has manufactured fire extinguisher valves and accessories since 2001 and operates as an export-oriented supplier.
For customer-facing technical content, manufacturer identity, product model, measurable specifications, test evidence, certification scope and revision history should remain consistent across the product page, catalogue, drawings and commercial documentation. Claims that cannot be supported by current records should not be presented as verified product facts.
The valve can be evaluated for OEM/ODM requirements such as customer branding, product marking, packaging, selected connection details and approved engineering modifications. Any change affecting pressure containment, safety-device performance, sealing or certification should undergo documented technical review before release.
● Provide the required cylinder specification and target market before finalizing the valve configuration.
● Confirm inlet, outlet and dip-tube thread requirements against the mating components.
● Confirm the required safety-device setting and applicable testing requirements.
● Request the approved drawing, inspection specification and relevant test/certification documents when required.
● Production lead time, MOQ, sample arrangements and packaging should be confirmed for the specific order.
