Stainless Steel (SS) Non-Return Valves (NRV) or check valves feature body materials like SS 304 or SS 316, pressure ratings up to 3000–6000 PSI, size ranges from 1/2' to 24', and operating temperatures from -40°C to 200°C, suited for water, oil, gas, and air. Core Material & Design Specifications • Material of Construction (MOC): SS 304 (CF8 / ASTM A351) or SS 316 (CF8M / ASTM A351) for higher corrosion resistance. • Size Range: Screwed/threaded types usually 1/2' to 2' (DN15 to DN50); flanged types up to 24' (DN600). • Pressure Rating: Standard industrial ratings span Class 150#, 300#, up to high-pressure 3000 PSI (210 bar) or 6000 PSI spring-loaded variants. • Temperature Range: Standard limits from -40°C up to +200°C depending on internal seal/seat material (PTFE, FKM, or metal-to-metal). Standards & Connections • Design Standards: Conforms to ASME B16.34 / BS 1868 / API 6D. • End Connections: Threaded (BSP, NPT, BSPP) or Flanged (ANSI B16.5 Class 150/300, DIN, JIS, PN16/PN25). • Testing & Inspection: API 598 / BS EN ISO 12266. If you need specifications for a particular size, end connection type (flanged vs. threaded), or pressure class, please let me know so I can narrow down the exact technical data sheet. AI responses may include mistakes.
