This American CO₂ Fire Extinguisher Valve is based on the product construction and technical information in the supplied reference document, adapted to the requested product name. The valve body is forged from a single copper rod, avoiding welded joints within the pressure-containing body. This construction is intended to provide a robust component for CO₂ service.
The squeeze-grip handle is shaped for practical manual activation. The spring-return mechanism is designed to return the valve toward the closed position when the handle is released. The external surface can be chrome-plated or nickel-plated according to customer requirements, providing a protective finish against atmospheric corrosion and surface wear.

The American CO₂ Fire Extinguisher Valve body is machined from a single copper rod billet through a hot-forging process. The reference document emphasizes the absence of weld seams in the pressure-containing envelope. This construction is presented as a means of reducing potential leak paths compared with multi-piece pressure-boundary assemblies.
Chrome or nickel electroplating is available for the external surfaces. The reference document describes the plating as a barrier against atmospheric corrosion and surface wear, with the finish selectable according to customer or market requirements.
The reference configuration shown for this American CO₂ Fire Extinguisher Valve uses 1-1/5NPT at the cylinder-side inlet, 3/8NPT at the discharge outlet, and 1/8-27NPS for the dip-tube connection. Thread specifications should be confirmed against the customer's cylinder, hose/horn, and dip-tube drawings before production.
The supplied reference document rates the original configuration for 2–7 kg/L CO₂ extinguishers. Because the requested product name is broader than that capacity designation, the exact cylinder capacity, neck thread, outlet connection, and applicable regulatory requirements should be confirmed before ordering an American-market configuration.
The valve is intended for carbon dioxide service. The source document states that copper and brass alloys are compatible with dry CO₂ under pressure and advises that other media should not be used unless material compatibility has been verified for the specific application.
According to the supplied reference, Ningbo Kaituo Valve Co., Ltd. has manufactured fire extinguisher valves and accessories since 2001 and operates an in-house quality inspection process. Quality control includes incoming copper-material inspection, in-process dimensional checks, pressure testing, and final inspection of thread dimensions, surface finish, and safety device set pressure.
Third-party pre-shipment inspection can be coordinated when required by the buyer. These process statements are based on the supplied reference document and should be matched to the specific inspection plan and purchase specification for each order.
● Thread specifications according to customer drawings
● Chrome-plated or nickel-plated surface finish
● Customer logo and required product markings
● Customized packaging
● Sample-based development and design review
For sample- or drawing-based projects, the engineering team can review the existing design and propose a matched or modified solution. Any changes affecting pressure performance, materials, threads, safety-device settings, or regulatory compliance should be technically validated before mass production.
● MOQ: 500 pcs for the standard specification; negotiable when combined with other accessories
● Samples: available for evaluation; freight is borne by the buyer
● Packaging: standard export carton or customized packaging
● Lead time: confirmed according to order quantity and production schedule
● Production updates: available after order confirmation
● After-sales: technical investigation and corrective-action support based on buyer feedback
The supplied reference specification covers 2–7 kg/L CO₂ extinguishers. For an American-market version with a different cylinder capacity or connection standard, the exact configuration should be confirmed with the manufacturer before ordering.
The supplied configuration uses 1-1/5NPT inlet, 3/8NPT outlet, and 1/8-27NPS dip-tube threads. Customer-specific threads can be developed from drawings or samples.
The reference document specifies 200 ±15 bar.
The reference document states approximately 174 bar at 20°C.
Yes. OEM and ODM options include threads, surface finish, branding/marking, packaging, and sample-based development.
The stated process includes incoming material inspection, in-process dimensional inspection, pressure testing, and final inspection. Third-party pre-shipment inspection can also be arranged upon request.
