01 / COMPANY
What this manufacturer offers
Sunfly’s Chinese company overview traces a workshop beginning in 1998 and creation of the Xinfan brand in 2001. It describes development from copper fittings and angle valves into brass distribution manifolds, thermostatic and radiator valves, mixing systems and complete heating solutions. These history statements distinguish the origin of the business and brand; they do not establish the incorporation date of today’s joint-stock entity.
The official contact page names 浙江鑫帆暖通智控股份有限公司 and publishes an address in the Qinggang industrial cluster, Yuhuan, Zhejiang. Its English navigation links the hosted catalogue where the identified XF20160H manifold has a readable specification. The manifold is a useful concrete reference for supplier qualification, but its component data cannot describe the whole company’s system offerings.
An original national-standard record also names this company as a drafting organisation for the current cold/hot-water manifold standard. Keep that contribution separate from a model-specific conformity report, a factory audit or a commitment to install and support a complete project.

03 / PROJECT REVIEW
Review the component configuration and system responsibility separately
A manifold, a mixing package and a complete system are different orders
The company’s catalogue separates manifolds, mixing systems, thermostatic valves, radiator valves and temperature-control panels/electric actuators. That range offers several potential purchasing scopes. Determine whether the contract concerns an identified component, a coordinated assembly or design/installation of a complete heating system.
Component supply
For XF20160H, specify ways, header and branch interfaces, material, pressure-temperature conditions, included parts and documentation. Its detail page provides a model identifier and connection figures.
Obtain an itemised pump/valve/control arrangement with its own selection data and interface drawing. These items are not established as included by the manifold page.
Complete heating solution
Agree heat-source and circuit design, site interfaces, installation/commissioning scope and responsible service parties. The overview’s solutions statement does not by itself define a project contract.
The overview identifies a process approach, not a current factory audit
Sunfly describes professional CAD design, precision machine tools and a complete product-management and inspection approach. It also gives patent and broad ISO/CE/“ROSH” certification statements. The readable overview does not identify a current certificate number, covered site/model schedule or a batch inspection record for XF20160H. The spelling on the source is not used here as proof of a particular chemical-compliance test.
Qualify the actual order with a current site/process description, approved drawings, material traceability and configuration-specific inspection plan. Ask how valves, seals, threaded connections and supplied adapters are identified and checked, and how design changes are controlled. Patent totals and engineering software names do not establish a supplied unit’s leakage performance or material conformity.
What the standard issuer confirms
The national standards platform lists 浙江鑫帆暖通智控股份有限公司 among the drafting organisations for GB/T 29730-2025, Distribution manifold of cold/hot water. It marks the standard current, published 1 August 2025 and implemented 1 February 2026, replacing GB/T 29730-2013.
This is original issuer evidence of participation and the applicable standard’s edition/status. It does not declare every Sunfly product compliant or supply a test report for a named order. If the buyer specifies that standard, require the supplier to identify the exact edition and provide the relevant model/configuration evidence. No complete technical-clause audit or independent factory test was performed by this platform.
Use XF20160H to test how clearly the supplier defines its offer
The English detail gives CW603N brass, nominal pressure up to 10 bar, working temperature up to 100°C, 2–12 ways and 50 mm spacing. It identifies an M30 × 1.5 actuator connection and branch options written as 3/4 inch × 16 or × 20. The detail does not provide hydraulic curves, an actuator electrical specification or a complete bill of materials.
A clear quotation should resolve these gaps rather than repeat the catalogue. The main photograph illustrates a five-way pair with white caps; it does not establish powered actuators or flowmeters included. Ask for the matching drawing, interface schedule, parts and versioned instructions. This concrete review helps distinguish a documented assembly from a generic brand-level capability claim.
Submit the circuit and connection schedule
Give the number of circuits, pipe sizes/materials, design flows and intended controls. State which accessories are to be included.
Review the identified assembly
Match header size, branch adapters, actuator compatibility, dimensions, limits and hydraulic evidence to the project.
Agree quality and handover
Confirm inspection/traceability requirements, current instructions, spare-part identifiers, warranty and service at the actual destination.
Resolve entity, document and service scope before a deposit
The official contact page’s direct text gives the Yuhuan address and names the joint-stock company. Its embedded third-party map search can display a different location result, which is not adopted as the factory address here. Reconcile the legal entity, actual production/delivery location and bank/contract documents through the supplier’s current approved information.
The source links an English catalogue on a web-hosting subdomain. That link establishes the catalogue’s connection to the Chinese site, but not a separate overseas legal entity or regional service organisation. Obtain current English drawings and instructions, the responsible commercial/technical contact, support arrangements and replacement terms for the ordered product. No destination-specific attendance promise or warranty duration was established in the reviewed sources.
