2507 National Standard Flange Ball Valve

Description

2507 (00Cr25Ni7Mo4N / S32750) is a “Super Duplex” steel with high chromium, molybdenum, and nitrogen content. It is engineered for the most demanding technical challenges:

• Elite Pitting Resistance: Boasts a PREN (Pitting Resistance Equivalent Number) of >40, ensuring exceptional performance in hot seawater and concentrated chlorides.
• Maximum Mechanical Strength: Provides even higher yield and tensile strength than 2205 duplex, allowing for thinner-walled, lighter-weight valves without sacrificing pressure integrity.
• Exceptional SCC Defense: Highly resistant to chloride-induced stress corrosion cracking and erosion-corrosion.

Features

• GB Standard Compliance: Fully compliant with GB/T 12237 (design), GB/T 9113 (flange), and GB/T 12221 (face-to-face), making it the ideal upgrade for domestic Chinese projects requiring high-end material performance.
• Full Bore Architecture: The full-port design ensures maximum flow capacity and is ideal for high-velocity flows or media containing particles.
• Bi-Directional Sealing: Equipped with precision-engineered seats that provide a zero-leakage seal in both directions, enhancing safety in critical processes.
• Low Torque Operation: Advanced seat design and mirror-polished ball finish ensure smooth, easy operation even under high differential pressures.

Specifications

Applications

• Marine & Offshore: Subsea pipelines, offshore oil platforms, and seawater desalination plants.
• Chemical Industry: Handling high-concentration nitric acid and organic acids at elevated temperatures.
• Petrochemical: Refineries and equipment handling sour crude and high-chloride production fluids.
• Energy: Flue gas desulfurization (FGD) systems in power plants.
