The Meticulous Process Behind FUWA Manufacturing

The superior performance and durability of FUWA industrial valves are a direct result of a rigorously controlled and technologically advanced manufacturing process. Every step, from raw material selection to final inspection, is meticulously executed to ensure the highest quality.

1. Material Selection and Sourcing

The foundation of any high-performance valve is its material. FUWA utilizes premium-grade materials selected for specific application demands. Common materials include:

• Carbon Steel (e.g., A216 WCB): For general industrial applications, offering good strength and cost-effectiveness.
• Stainless Steel (e.g., A351 CF8M, Duplex/Super Duplex): For corrosive environments, high-temperature service, and applications requiring superior hygiene.
• Alloy Steel (e.g., A217 C5, C12): For high-temperature, high-pressure services in power generation and petrochemicals.
• Exotic Alloys (e.g., Hastelloy, Inconel): For extremely aggressive chemical services, severe corrosion, and ultra-high temperature/pressure applications.

2. Core Manufacturing Processes

The main body and critical components of FUWA valves undergo precision manufacturing:

• Casting: For complex valve body shapes, high-integrity castings are produced using advanced sand casting or investment casting techniques. Strict control over molten metal composition and cooling rates prevents defects.
• Forging: For components requiring maximum strength and ductility (e.g., stems, bonnets), forging processes reshape metal through localized compressive forces, resulting in superior grain structure and mechanical properties.
• CNC Machining: Computer Numerical Control (CNC) machining ensures precise dimensional accuracy and smooth surface finishes for critical parts like seats, discs, and stems. This process is vital for achieving tight tolerances and leak-free performance.
• Welding: For fabricated bodies or joining dissimilar metals, advanced welding techniques (e.g., TIG, MIG, SAW) are employed by certified welders, followed by post-weld heat treatment (PWHT) where necessary to relieve stress.
• Heat Treatment: Various heat treatment processes (e.g., annealing, normalizing, quenching and tempering) are applied to optimize material properties such as hardness, toughness, and corrosion resistance.

3. Assembly and Testing Standards

Following individual component manufacturing, FUWA valves are meticulously assembled in clean environments. Comprehensive testing ensures compliance with international standards:

• Non-Destructive Testing (NDT): Includes radiographic testing (RT), ultrasonic testing (UT), magnetic particle testing (MT), and liquid penetrant testing (PT) to detect internal and surface flaws in castings and welds.
• Hydrostatic Pressure Testing: Each valve is subjected to pressure testing at 1.5 times the nominal pressure rating to verify body strength and external leak integrity, as per API 598 or EN 12266.
• Seat Leakage Testing: Air or water is used at lower pressures to confirm the tight sealing capability of the valve seat.
• Fugitive Emissions Testing: For critical applications, valves undergo rigorous testing to ensure minimal stem seal leakage, meeting standards like ISO 15848-1.
• Cycle Testing: Select valves are subjected to thousands of open-close cycles to simulate operational lifespan and verify long-term reliability.
• Adherence to Standards: All manufacturing and testing strictly comply with international standards such as ISO 9001 (Quality Management), API (American Petroleum Institute), ANSI (American National Standards Institute), ASME (American Society of Mechanical Engineers), and EN (European Standards).

4. Service Life and Target Industries

The expected service life of a FUWA valve, when properly selected and maintained, typically ranges from 10 to 30 years, depending on the application severity and operational frequency. This extended lifespan contributes significantly to a lower TCO.

Target industries benefiting from FUWA’s robust solutions include:

• Petrochemical: Refineries, chemical plants, oil & gas extraction and processing, where high-pressure, high-temperature, and corrosive media handling are routine.
• Metallurgy: Steel mills, non-ferrous metal processing, requiring valves for high-temperature gases, water cooling, and abrasive slurries.
• Water Supply & Drainage: Municipal water treatment, wastewater management, desalination plants, requiring reliable flow control for large volumes and often corrosive water.
• Power Generation: Thermal, nuclear, and renewable energy plants, demanding valves for steam, boiler feed water, and turbine control under extreme conditions.
• Pulp & Paper: Handling abrasive slurries and corrosive chemicals in pulp processing.

In these scenarios, FUWA valves demonstrate advantages such as superior corrosion resistance due to specialized alloys, significant energy saving through optimized flow paths reducing pressure drop, and enhanced safety through robust design and zero-leakage capabilities.

Technical Specifications of High-Performance FUWA Industrial Valves

Understanding the precise technical parameters of FUWA valves is crucial for engineers and procurement specialists to ensure optimal selection for specific operational requirements. Our product line encompasses a range of designs, each engineered for peak performance.

Key Technical Terminology Explained:

• Nominal Pressure (PN/Class): Defines the maximum permissible operating pressure at a given temperature, categorized by pressure classes (e.g., Class 150 to Class 2500 for ASME, PN10 to PN420 for EN).
• Nominal Diameter (DN/NPS): Indicates the approximate size of the bore, with DN (Diamètre Nominal) used in metric and NPS (Nominal Pipe Size) in imperial.
• Cv Value (Flow Coefficient): Represents the flow rate of water (in GPM) at 60°F (15.5°C) that will result in a 1 psi pressure drop across the valve. A higher Cv value indicates better flow efficiency.
• Temperature Range: The minimum and maximum temperatures the valve can safely withstand, dependent on material selection and sealing components.
• Leakage Class: Categorizes the permissible seat leakage rate, with Class VI (bubble-tight) being the most stringent.
