The Fire Extinguisher Valve for 2-7KG is engineered as a pressure-containing control component within a complete fire extinguisher system. Its function is to provide controlled manual actuation and the required interfaces for the cylinder, dip tube and discharge assembly.
For reliable assembly, the valve configuration should always be matched with the corresponding cylinder specification, dip tube, discharge component, operating pressure, temperature requirements and approved engineering documentation. Thread designation alone should not be used as the sole basis for interchangeability.

Designed for portable fire extinguisher assemblies in the 2-7 kg nominal filling range.
Manual squeeze-grip operation for direct valve actuation.
PZ27.8 inlet connection.
W21.8-14 outlet connection.
M10×1 dip-tube connection.
Specified safety-device setting of 200±15 bar.
Configuration suitable for OEM/ODM review, subject to engineering approval.
Technical specifications can be aligned with controlled drawings and inspection requirements.
The supplied reference material describes the valve family as using a forged copper-alloy valve body. The final alloy designation, forging condition, machining tolerances and surface finish should be controlled by the approved bill of materials and production drawing.
The manual squeeze-grip handle provides the operator interface for valve actuation. Handle travel, operating force, spring characteristics and internal sealing details should be controlled through the approved design and production inspection procedure.
The specified configuration uses PZ27.8 at the inlet, W21.8-14 at the outlet and M10×1 for the dip-tube connection. Mating components should be checked for thread standard, engagement, sealing method and dimensional compatibility before assembly.
This valve is a component of a complete fire extinguisher assembly. Product suitability depends on the complete system design rather than the valve alone. Before production or installation, confirm compatibility with the cylinder, extinguishing medium, dip tube, discharge assembly and applicable pressure and temperature requirements.
Use only with compatible and approved mating components.
Verify thread compatibility and sealing requirements before assembly.
Use the valve only within its approved design and operating limits.
Do not alter the safety-device setting without documented engineering approval.
Perform pressure and leakage testing according to the approved test procedure.
Installation, filling and servicing should be performed by qualified personnel.
To support traceability and technical confidence, the recommended verification sequence includes:
Incoming material and component inspection against the approved specification.
Dimensional inspection of PZ27.8, W21.8-14, M10×1 and other critical characteristics.
Inspection of sealing surfaces, internal passages and operating mechanism.
Pressure and leakage testing according to the approved procedure.
Verification of safety-device configuration and specified setting.
Final inspection of marking, appearance, configuration and packaging.
Retention of inspection and traceability records where required.
Third-party inspection or testing when required by the customer or project.
OEM/ODM requirements can be reviewed for customer branding, product marking, packaging, handle appearance, surface finish and approved engineering modifications. Changes that may affect pressure containment, sealing, safety-device performance or certification should be subject to documented technical review and approval before production release.
For technical buyers and engineering teams, product information should be supported by controlled documentation rather than unsupported marketing claims. Depending on the project, the following documents may be available on request:
Approved product drawing and revision-controlled specification.
Material and dimensional inspection information, where applicable.
Pressure and leakage test records, where applicable.
Certification or third-party test documentation when valid for the exact configuration.
Packaging, marking and traceability requirements.
Customer-specific technical or inspection requirements.
The product name and technical description do not by themselves establish CE, TÜV or other certification. Any certification or conformity statement should be supported by current documentation covering the exact production configuration and intended market.
For regulated markets, customers should confirm the requirements applicable to the complete fire extinguisher assembly, including pressure equipment, testing, marking and component conformity obligations. Certification scope should not be inferred from the presence of a mark, logo or general product-family statement.
For procurement and engineering teams, the most important configuration points are the connection interfaces and safety-device setting. Clear identification of PZ27.8, W21.8-14, M10×1 and 200±15 bar helps reduce specification ambiguity during sourcing, assembly and inspection. Final interchangeability still depends on the complete mating-component design.
