1. Design Parameters and Dimensional Control
The IFAN 3 Ways Brass Water Manifold is engineered with a T-type or linear configuration, integrating a main inlet with three outlet ports. The design conforms to internal dimensional guidelines based on EN ISO plumbing part conventions and tolerances. The center-to-center spacing between outlets, thread dimensions, and overall body geometry are maintained within strict tolerances of ±0.05 mm. This ensures accurate alignment during system assembly and minimizes the risk of cross-threading or connection misalignment. CAD-based design and precision CNC modeling are employed to simulate water flow and structural load distribution across all ports.
2. Brass Composition and Material Certification
Each manifold is manufactured from high-grade CW617N or HPb59-1 brass, known for its machinability and corrosion resistance. Incoming raw material billets are tested for composition using X-ray fluorescence spectrometry to ensure compliance with EN 12164/12165 standards. Trace elements such as lead, bismuth, and arsenic are strictly controlled to meet potable water requirements. Material traceability is maintained through heat number tagging. The brass undergoes forging or casting, depending on the model, followed by post-treatment such as annealing to relieve internal stress before machining begins.
3. Threading Precision and Compatibility Assurance
The inlet and outlet ports of the 3-way manifold are machined with ISO 228 (BSPP) or NPT standard threads based on regional demand. Threads are cut on high-precision CNC equipment, with in-process monitoring of pitch, minor diameter, and angle. Each threaded section is verified using certified go/no-go gauges, and a torque test is conducted to confirm thread holding strength under typical installation loads. Surface roughness of threaded regions is maintained below Ra 1.6 µm to ensure proper sealing when used with PTFE tape or thread sealant.
4. Internal Flow Path and Hydraulic Design
The internal bore of the manifold is designed to reduce flow resistance and turbulence. The central channel connects symmetrically to each outlet, with a uniform bore diameter calculated to preserve flow consistency across all branches. IFAN applies computational fluid dynamics (CFD) modeling to test internal hydraulic behavior before tooling. The transition between main and branch ports is chamfered to minimize eddies and optimize velocity distribution. Each port is designed with a full-bore structure to avoid restriction in volumetric flow and pressure loss.
5. Surface Finishing and Anti-Corrosion Treatment
To protect against environmental exposure, IFAN applies multi-step surface treatments to the brass body. These include degreasing, mechanical polishing, acid passivation, and optional nickel or chrome plating. Surface plating thickness is measured with eddy current devices and must meet a minimum of 10 μm in plated variants. The finish undergoes salt spray tests in accordance with ISO 9227 to verify corrosion resistance. The bare brass models are also treated with anti-oxidation coatings to prevent surface tarnishing during long-term storage and transit.
6. Pressure Resistance and Leak Testing
Each IFAN 3 Ways Brass Water Manifold is subjected to a series of pressure tests before packaging. Static pressure testing is performed at 1.5× the rated working pressure-typically 15 bar-to confirm leak-free performance across all connections. Test media include clean water and compressed air, depending on the evaluation phase. Leak inspection is conducted visually and electronically, using bubble immersion and electronic leak sensors. A subset of each batch undergoes burst testing, where pressure is increased until failure to validate safety margins above rated values.
7. Port Alignment and Structural Tolerance Verification
All manifolds undergo dimensional inspection using coordinate measuring machines (CMMs) and digital calipers. Key parameters include port center spacing, perpendicularity of branches, and overall length consistency. The perpendicular angle of each outlet to the manifold body is measured to ensure correct spatial orientation during installation. Out-of-tolerance parts are isolated and reviewed for machining calibration or tooling wear. These checks are repeated at fixed intervals across the production batch, in line with ISO 2859-1 statistical sampling protocols.
8. Valve Interface and Optional Component Integration
The 3-port manifold is designed to optionally accommodate mini ball valves or check valves at each outlet. The outlet threads are tested for concentricity and depth to allow seamless valve installation. Models that include pre-installed valves undergo an additional pressure and actuation test to confirm valve performance. Valves are installed using calibrated torque tools, and a sealing inspection is performed to ensure O-ring or PTFE engagement. This modular compatibility expands the manifold's adaptability without requiring further structural modification.
9. Marking, Traceability, and Product Labeling
Each IFAN 3 Ways Brass Water Manifold is marked with a laser-etched batch number, size specification, and flow direction symbol. These markings are tested for legibility after exposure to water, heat, and mechanical abrasion. The manifold body may also include cast-in or engraved IFAN branding for visual authentication. Traceability is maintained from raw material through to finished product using ERP-linked barcoding. All packaging includes a QR code linked to the product certificate, test records, and installation instructions, ensuring full documentation control.
10. Cleanliness, Handling, and Packaging Control
Before final packaging, the manifolds undergo ultrasonic cleaning to remove machining oils, metal chips, and contaminants. Cleanliness is verified with fiber-optic visual inspection and surface residue testing. Units are individually bagged or boxed in foam-lined cartons to prevent thread damage during transit. Desiccant packets are included in bulk shipments to prevent oxidation. Final quality assurance includes drop testing of packaged units and vibration testing in simulated transport conditions. Labeling includes part number, thread type, pressure class, and production date.
Conclusion: Dimensional Integrity and Controlled Engineering
The IFAN 3 Ways Brass Water Manifold is engineered for reliability, hydraulic balance, and dimensional precision. From high-grade brass selection and exact CNC machining to thread control, surface finishing, and pressure validation, every production step is executed under strict quality protocols. With integrated traceability and modular compatibility, this manifold type reflects IFAN's manufacturing focus on consistency, technical detail, and durable construction, ensuring it meets the demands of professional-grade plumbing installations worldwide.
