从India供应商批量进口A217 Ca15 Cast Alloy Steel Swing Check Valve

The A217 CA15 cast alloy steel swing check valve from SQK Valves Fittings & Automation Private Limited is designed for unidirectional flow control in industrial piping systems. Manufactured from ASTM A217 CA15 martensitic stainless steel, this valve offers good corrosion resistance and mechanical strength at moderate temperatures. The swing check mechanism uses a hinged disc that opens with forward flow and closes by gravity to prevent backflow, protecting pumps and compressors from damage. Pressure ratings and exact port dimensions should be confirmed with the supplier for your specific line size.

CA15 alloy contains approximately 11.5-14% chromium with controlled carbon content, providing hardness and wear resistance typical of martensitic grades. The cast construction allows complex internal geometries for smooth flow patterns with minimal pressure drop. Standard industry practice includes full port or reduced bore configurations; face-to-face dimensions typically comply with ASME B16.10 for interchangability. Seat surfaces may be overlaid with stellite or similar hard-facing for extended service life in abrasive media. Gasket surfaces are usually raised face or ring joint depending on pressure class.

This valve type serves oil and gas production, petrochemical refining, water treatment, and power generation facilities where backflow prevention is critical. Buyers typically specify end connections (flanged, butt weld, or socket weld), pressure class (commonly Class 150-600 per ASME), and inspection standards such as API 598 or MSS SP-71.
