The Stainless Steel Handle CO2 Valve is intended for portable CO₂ fire extinguishers in the 2–5 kg filling range. It functions as the cylinder-head valve and integrates the cylinder connection, discharge connection, dip-tube interface, operating mechanism and pressure-relief device into one assembly.
The stainless steel handle is positioned as the product's distinguishing operating feature. Its configuration can be specified according to customer requirements, subject to the applicable design and manufacturing parameters.
According to the reference document, the valve body is produced from high-quality brass (HPb59-1 or equivalent). The manufacturing route includes forging, CNC precision machining, grinding, polishing, electroplating, assembly and functional testing. These processes are used to maintain dimensional consistency, sealing performance and repeatable assembly quality.
For the stainless steel handle configuration, the handle material and geometry should be confirmed against the customer's approved drawing or sample before mass production. This approach supports traceability and avoids treating a customized configuration as a universal standard specification.

The reference configuration incorporates a burst-disc safety device set at 200 ± 15 bar. The device is intended to provide pressure relief in an over-pressure condition. Actual pressure requirements depend on the extinguisher cylinder design, applicable standard and test conditions; the valve should therefore be matched to the approved cylinder specification rather than selected from pressure figures alone.
The supplied reference states an operating-temperature range of –30°C to +60°C and identifies EN 3-7 as the relevant reference for the stated European-market configuration. Certification and compliance claims should be supported by current certificates and test reports for the exact model/configuration supplied.
● Material control: controlled brass alloy composition for the valve body and documented handle material/configuration.
● Precision machining: CNC machining of threads, sealing surfaces and internal passages.
● Surface treatment: grinding, polishing and chrome or nickel electroplating where specified.
● Assembly control: controlled assembly torque and inspection of the lever mechanism and safety-device seating.
● Functional testing: verification of safety-device activation pressure within the specified range.
● Leak testing: inspection of sealing integrity at the cylinder–valve interface and outlet connection.
● Batch inspection: dimensional and functional checks are performed for production batches.
The supplied reference document identifies CE, TÜV and ISO 9001 as applicable credentials for the referenced valve configuration. For website publication and customer qualification, the specific certificate number, issuing organization, scope, validity period and covered model should be verified against current documentation before making a certification claim.
For European-market applications, the reference document identifies EN 3-7 as a relevant market requirement. Compliance should be evaluated for the complete extinguisher assembly and the exact valve/cylinder combination, not inferred from the valve name alone.
The valve is intended for 2–5 kg CO₂ portable fire extinguishers. The reference application environments include electrical equipment areas such as server rooms, data centers, switchgear cabinets and substations; industrial locations such as laboratories and precision-instrument rooms; marine engine-room and fuel-storage environments; and other applications where CO₂ extinguishing equipment is specified.
Installation should be performed by qualified personnel using the cylinder manufacturer's approved procedure. The 1-1/8UNF inlet connects to the cylinder neck, the 1/8NPS connection is used for the dip tube, and the 5/8UNF outlet connects to the discharge assembly. Sealing method and tightening torque should follow the approved cylinder/valve specification.
● Inspect the valve body and handle for corrosion, deformation or mechanical damage.
● Check that the burst-disc safety device remains intact and unobstructed.
● Confirm smooth and reliable operation of the lever mechanism.
● Check for leakage at the cylinder–valve interface and outlet connection.
● Replace an activated or damaged burst disc in accordance with the approved maintenance procedure.
● Use qualified service personnel and follow applicable local fire-safety regulations.
ANKE provides OEM and ODM support for fire-extinguisher valve applications. Depending on project requirements, customization may include stainless steel handle style, handle color or finish, surface plating, thread configuration within the applicable design range, safety-device setting within applicable requirements, dip-tube length and connection details.
For new development, customers can provide technical drawings, cylinder specifications or an existing valve sample. Engineering review should confirm thread compatibility, pressure parameters, material requirements and regulatory requirements before production approval.
The reference configuration is designed for 2–5 kg CO₂ fire extinguishers, approximately 2–5 L cylinder volume.
This product is specified with a stainless steel operating handle while retaining the brass valve-body construction described in the supplied reference.
The reference configuration uses 1-1/8UNF inlet, 5/8UNF outlet and 1/8NPS dip-tube threads.
The reference specification lists a burst-disc setting of 200 ± 15 bar. Final selection must match the approved cylinder and applicable requirements.
Yes. The reference document identifies customization of handle style/color and plating type, together with other project-specific parameters.
The reference document states a standard MOQ of 500 pieces, with possible negotiation when combined with other fire-extinguisher accessories.
