Products Description
Plug-and-Play HVAC Stop Valve Assemblies
Streamline Your Factory Assembly
As a crucial connection point between indoor and outdoor units, the stop valve regulates refrigerant flow and isolates the circuit for maintenance. Our pre-assembled valve kits go a step further—designed specifically to accelerate your AC manufacturing process.
⚠️ Value-Added Service: Turnkey Sourcing & Brazing
Support customer-designated brand valve body sourcing and brazing. We can procure your preferred brands (e.g., Sanhua, Danfoss) and expertly braze them onto customized copper pipe configurations.🚀 Save Assembly Line Labor Costs
Plug-and-Play integration with charging ports and flange brackets. By pre-brazing the charging valve and mounting flange directly onto the assembly, we eliminate extra installation steps on your production line, significantly reducing your factory labor hours.Product Features
- Reduced Assembly Complexity: Integrating the charging port (one-way valve) and mounting flange into a single, ready-to-install unit means fewer parts to manage and fewer welding points on your line.
- Advanced Sealing Technology: Utilizes imported, high-quality sealing materials that are highly resistant to aging, ensuring zero leakage under high-pressure refrigerants.
- Reliable Flow Control: Features a precision-machined valve stem that guarantees smooth operation and absolute system isolation during after-sales service.
Application Scope

* Note: Dimensions and specifications are subject to customization based on customer requirements.
Q:1.Do you provide CE/UL certificates for the entire kit?
A: We provide UL/CE certified modules (like filter driers and charge valves) sourced directly from top-tier manufacturers. The certificates and test reports for these specific components come with the shipment. For non-electrical parts (like copper pipes and brackets), we provide material reports and d
Q:2.Are electrical cables included in the kit for the local market?
A: No. To ensure strict compliance and avoid regional electrical certification conflicts (such as CE/UL cable standards), electrical cables are intentionally excluded from our standard mechanical kits. This allows you to source local, fully certified cables and integrate them on your line, keeping your
Q:3.What exactly is included in your standard "Line Set Kit"?
A: Our standard kit includes five core mechanical modules: Y-Joints (or tees), pre-cut copper pipes with insulation, filter driers, charge valves, and vibration eliminators. Optional modules like sight glasses or accumulators are available upon request. We pack them according to your specific machine B
Q:4.Can you customize the copper pipe lengths and kit composition?
A: Yes. Because we aggregate from a flexible, top-tier supply chain, we can customize the copper pipe lengths (pre-cut and flared), insulation thickness, and the specific combination of components based on your exact assembly drawings. You don't need to meet a massive MOQ for the whole kit; we scal
Q:5.How do you handle the shipping and customs clearance documents?
A: Since a kit involves multiple HS codes (copper fittings, valves, brackets), we coordinate the commercial invoice and packing list clearly by item. We work closely with your freight forwarder to ensure the customs declaration matches the physical goods exactly, minimizing the risk of port delays. All
Q:6.What is the typical lead time for a BOM-matched kit?
A: After BOM confirmation and sample approval, the production of the core modules typically takes 20–30 days. Because we consolidate modules at our facility before shipping, you save the time you would normally waste waiting for different factories to deliver to your forwarder. We provide a single, un
