The Non Return Valve Class 1500, Swing Type with Bolted Cover, is designed for ultra-high-pressure applications where flow reliability and equipment protection are critical. Built to handle extreme pressures, this valve prevents reverse flow and protects pumps, compressors, and pipelines from potential damage.
Manufactured using premium-grade materials like WCB, CF8M, and SS 316, it ensures corrosion resistance and long service life. The swing-type disc provides smooth flow operation with minimal pressure drop, while the bolted cover allows easy access for maintenance, ensuring long-term durability and safety in harsh environments.
Key Features:
Valve Type: Swing Type Non Return Valve (NRV)
Pressure Rating: Class 1500
Body Materials: WCB, CF8M, SS 316, and other alloys
End Connections: Flanged (ANSI B16.5) or Butt Welded (ASME B16.25)
Cover Type: Bolted Cover
Design Standard: API 6D / ASME B16.34
Applications: Oil & Gas, Power Generation, Petrochemical, Steam Systems
Leakage Class: Class VI
Temperature Range: Up to 450°C (material dependent)
Engineered for high-pressure critical operations, the Class 1500 Swing Type Non Return Valve is the trusted solution for backflow prevention in the most demanding industrial environments.
