Professional FAQ: Industry Terminologies
Q1. What is aluminum bronze and why is it used for gate valves?
Aluminum bronze is a copper-based alloy (typically Cu-9~12% Al, with small Fe/Ni/Mn additions), conforming to ASTM B148 C95800. Its superior corrosion resistance, especially in marine and chemical processing environments, makes it preferred for aluminum bronze gate valve applications over standard bronze or cast iron.
Q2. What does BB, RS, OS&Y stand for?
BB stands for Bolted Bonnet (easy maintenance, pressure-tight), RS means Rising Stem (stroke visible for safety), and OS&Y is Outside Screw & Yoke — a design where the stem thread is outside valve flow to prevent corrosion/wear. These features are standard in high-reliability gates like those from Fivalco OS&Y and Gate valve BB RS OS&Y in bronze or brass.
Q3. What are the main standards regulating aluminum bronze gate valves?
ISO 9001 (quality management), API 600/API 598 (design/testing), EN 12266-1 (leak tightness), ANSI B16.34 (pressure/temperature rating), and NACE MR0175 for anti-corrosion in sour gas/oil applications.
Q4. How is valve size selected for my application?
Valve size depends on required flow rate, pressure drop, and end connection type. For seawater, mining, and chemical applications, typical ranges are DN15–DN400. For retrofits, verify face-to-face and flange compatibility per ANSI/EN standards.
Q5. What end connections are available?
Standard options include flanged (ANSI/EN), threaded (BSP/NPT), and grooved ends. Most aluminum bronze gate valve models support both flanged and threaded for maximum site flexibility.
Q6. What is typical service life and maintenance?
With C95800 material and ISO/API testing, typical service life is 25+ years, especially in marine and desalination sectors. Routine inspection, lubrication and packing adjustments recommended every 12–18 months for continuous service.
Q7. Are certifications and third-party inspections available?
Yes. All aluminum bronze gate valve batches can be supplied with EN 10204 3.1/3.2 material certificates, API/ISO test certificates, and witnessed by authorities like TÜV, DNV, Lloyd’s, SGS for full traceability and export compliance.
