2507 Super Duplex American Standard Globe Valve is an elite flow-control solution designed for extreme industrial service. Engineered in full accordance with API 623 and ASME B16.34, this valve utilizes 2507 Super Duplex Stainless Steel to provide unmatched mechanical strength and superior resistance to localized corrosion in high-pressure, high-chloride environments.
Description
2507 (UNS S32750) is a premier ferritic-austenitic alloy designed for applications requiring exceptional strength and corrosion resistance:
- High Yield Strength: The mechanical strength of 2507 is significantly higher than standard 300-series stainless steels, allowing for a robust valve body that handles extreme pressure cycles.
- Elite Pitting Resistance: With a PREN (Pitting Resistance Equivalent Number) of $\ge$ 40, it offers maximum protection against pitting and crevice corrosion in seawater and brine.
- SCC Defense: The balanced dual-phase microstructure provides high immunity to chloride-induced stress corrosion cracking (SCC).
Features
- Advanced Throttling Capability: Featuring a precision-engineered cone valve disc, this valve is optimized for superior throttling. The conical shape allows for gradual flow adjustment, making it the preferred choice for systems requiring fine-tuned flow regulation.
- “Low-In, High-Out” Flow Pattern: Designed so the medium enters below the disc and exits above it. This ensures that the pressure assists in opening the valve and reduces wear on the packing when the valve is closed.
- API/ASME Compliance: Fully compliant with API 623 (design), ASME B16.10 (face-to-face), and ASME B16.5 (flanges), ensuring global interchangeability and safety in high-pressure piping.
- Versatile Operation: Can be equipped with manual handwheels, gear transmissions, or pneumatic/electric actuators to meet diverse automation requirements in complex plants.
