Description

The API Stainless Steel Swing Check Valve is a critical industrial component designed to prevent backflow and protect downstream equipment such as pumps and compressors. Constructed from high-quality stainless steel (CF8), this valve utilizes a hinged disc mechanism that swings open to allow forward flow and automatically closes against the seat to block reverse flow. Its robust design ensures reliable performance in harsh environments, offering excellent corrosion resistance and durability for demanding applications.
Technical Specifications:
  • Pressure Class: Class 150 (ASME B16.34)
  • Size Range: NPS 2″ to 24″ (DN50 to DN600) (Standard industry range)
  • Applicable Medium: Water, Steam, Oil, Gas, and corrosive fluids
  • Operating Temperature: -29°C to 425°C (Stainless Steel CF8 Range)

Key Product Features:
  • Effective Backflow Prevention: The swinging disc mechanism automatically closes upon flow reversal or stoppage, utilizing gravity and reverse pressure to seal the valve instantly.
  • Superior Corrosion Resistance: Manufactured from ASTM A351 CF8 stainless steel, providing excellent resistance to rust and corrosion in harsh chemical and marine environments.
  • Low Pressure Drop: When fully open, the disc swings completely out of the flow path, minimizing resistance and pressure loss.
  • Durability & Reliability: Designed to withstand high pressures and temperatures, ensuring long-term service life and minimal maintenance requirements.
  • Compliance: Meets rigorous industry standards (API/ASME) for safety and performance
Applications:
Ideal for preventing backflow in Oil & Gas, Petrochemical, Power Generation, and Water Treatment systems. Specifically designed to protect pumps, compressors, and other sensitive equipment from damage caused by reverse flow in pipelines handling corrosive or high-temperature media.
