2-9KG CO2 Fire Extinguisher Valve

Suitable for 2KG to 9KG specifications of CO2 fire extinguishers. The 2-9KG CO2 Fire Extinguisher valve is made of copper alloy and can be customized according to customer needs. The surface treatment is chrome plating or nickel plating. The working pressure range is 150-250 BAR, and the pressure is between 225 BAR and 315 BAR. The bottleneck thread specification is PZ27.8/25E/M25*2, the outlet thread specification is W21.8-14, and the suction pipe thread specification is M10X1/G1/4. This valve is equipped with a safety pressure relief device, which can release the pressure when the pressure reaches 225±15 BAR, effectively preventing the fire extinguisher from overpressure and potential explosion risks. The product is carefully designed to ensure effectiveness and safety in hazardous environments. It has the characteristics of reliability, making it an ideal choice for hazardous environments.

Product Parameters

Designed for 2–9KG CO₂ Fire Extinguishers

The 2045 valve is specified for CO₂ fire extinguishers with capacities ranging from 2 kg to 9 kg, subject to confirmation of the approved cylinder and valve configuration.

Potential application environments for compatible CO₂ extinguishers include:

· Commercial buildings and facilities.

· Electrical equipment areas where CO₂ extinguishers are approved for use.

· Industrial equipment rooms.

· Laboratories and technical facilities.

· Commercial and industrial fire protection equipment.

· OEM CO₂ extinguisher manufacturing and assembly lines.

CO₂ extinguishers are commonly used for certain Class B flammable-liquid fires and energized electrical equipment where permitted by the applicable equipment instructions and safety regulations. They are not universally suitable for every fire type or environment.

Quality Assurance and Documentation

For high-pressure fire protection components, verifiable documentation is essential to product evaluation and supplier qualification.

Depending on the product configuration and available records, supporting documentation may include:

· Copper alloy material identification and relevant certificates.

· Approved technical drawings and product specifications.

· Thread dimensional inspection records.

· Applicable pressure and leakage test reports.

· Pressure relief device test records.

· Batch identification and traceability records.

· Relevant quality management system documentation.

· Product certification and conformity documentation, where required.

Certificates should be checked for issuing organization, scope, validity, applicable product model, and manufacturing site. Company-level management system certification should not be represented as product-specific certification unless the documentation explicitly covers the product.

For export orders, the target market, applicable cylinder and valve standards, and required product approvals should be confirmed before production.

After-Sales Service and Long-Term Cooperation

Long-term supply relationships depend on consistent specifications, technical support, and transparent quality management.

Depending on the supplier's actual service arrangements, support may include:

· Technical assistance with inlet, outlet, and accessory thread selection.

· Review of drawings and cylinder compatibility.

· Sample confirmation before bulk production.

· Clarification of pressure and relief device specifications.

· Assistance with relevant inspection and quality documentation.

· Communication regarding quality concerns and corrective-action procedures.

· Support for repeat orders and approved design changes.

For customized high-pressure valve projects, technical approval should be completed before production. Any change affecting materials, connections, pressure ratings, or relief device settings should be reviewed by qualified personnel and assessed for its effect on compliance and safety.
