Brass Foot Valves Manufacturing Process (With Flow Chart)
Stepwise Manufacturing Process:
1. Brass Bar / Ingot Selection (CW617N, CW614N)
➜
2. Hot Forging / Sand Casting
➜
3. CNC Machining & Drilling
➜
4. Precision Threading (BSP/NPT)
➜
5. Mesh/Strainer Fitting (304 SS/Brass)
➜
6. Pressure/Leak Testing (ISO 5208)
➜

Technical Comparison: Brass Foot Valves vs. Alternatives
Application Case: Brass Foot Valves in Water Treatment
A municipal waterworks in India replaced aging cast iron valves with brass foot valves (2", 3", CW617N, 304 SS mesh). After 18 months of operation:
- Energy savings up to 17.2% due to reduced backflow drag;
- No failure/maintenance compared to 2-3 breakdowns per year previously;
- Service life estimated to exceed 9 years—confirmed by accelerated aging/pressure tests.
End-user's feedback: "Brass foot valves significantly reduced downtime. Installation was easy, and water quality stability improved."

FAQ: Professional Knowledge on Brass Foot Valves
1. What is the best material grade for brass foot valves in marine or high-corrosion environments?
DZR (Dezincification Resistant Brass: CW602N) is recommended for saline or aggressive fluids, meeting ASTM B453 and ISO 6509 standards. It resists zinc leaching and ensures a lifespan of 10+ years in harsh conditions.
2. What are typical mesh/strainer choices and significance?
304 SS mesh (standard 30-60 mesh, up to 120-micron for fine filtration) provides superior corrosion resistance and particle filtration, critical when pumping river/lake water or in irrigation systems.
3. How are brass foot valves tested for quality?
100% factory hydraulic/air testing at 1.5x working pressure per ISO 5208 and ANSI B16.34. Leakage, body strength, and seat integrity are verified. Material certification (EN10204 3.1) ensures full traceability.
4. What mounting standards are supported?
Brass foot valves are supplied with BSP, BSPT, and NPT threads as per ISO 228/1 and ANSI/ASME B1.20.1. This ensures compatibility with international piping systems and pump inlets/outlets.
5. What’s the recommended installation orientation?
Install vertically at the lowest suction point in water tanks, wells, or pipelines for optimal backflow prevention. Ensure the arrow direction matches the liquid flow.
6. What is typical warranty and after-sales support?
Standard warranty is 24 months for brass foot valves under normal use. Technical support, replacement, and on-site troubleshooting are provided by major manufacturers. Extended warranty available for bulk/OEM projects.
7. Are brass foot valves suitable for potable (drinking) water?
Yes, models certified to ANSI/NSF 61 or EN 13828 meet potable water standards, and are widely used in municipal and building water supply projects.
