Import A351 Cn7m Alloy 20 Ball Valve — Buy in Bulk from Supplier in India

The A351 CN7M Alloy 20 Ball Valve from SQK Valves Fittings & Automation Private Limited is engineered for corrosion resistance and precise flow control in demanding industrial environments. This quarter-turn valve is cast from A351 CN7M Alloy 20, a nickel-iron-chromium alloy with copper and molybdenum additions, providing exceptional resistance to sulfuric acid, phosphoric acid, and chloride-induced pitting. Its full-bore design ensures minimal pressure drop, while the blowout-proof stem and live-loaded packing system prevent leakage under high-pressure conditions.

Alloy 20 ball valves are typically supplied with a PTFE or reinforced PTFE seat for chemical compatibility, and the body material conforms to ASTM A351 for castings. Standard end connections include flanged ASME B16.5 or socket-weld configurations, with pressure ratings up to Class 150 or Class 300 as per the valve series. The valve’s internal components are often hardened and polished to reduce wear and ensure long service life in abrasive or corrosive media.

These valves are primarily used in chemical processing, pharmaceutical manufacturing, and food and beverage production where aggressive fluids require reliable isolation. Buyers typically source them for applications involving sulfuric acid handling, pulp and paper production, or seawater systems. Sourcing from India offers competitive lead times for bulk orders, with common trade terms including FOB or CIF. Confirm packaging specifications, as industrial valves are often crated or palletized to prevent damage during transit.

SQK Valves Fittings & Automation Private Limited is an India-based supplier specializing in industrial valves, fittings, and automation solutions. The company operates as an imported-tier supplier with a focus on corrosion-resistant alloys, including Alloy 20, Hastelloy, and duplex stainless steels. Its product range covers ball valves, gate valves, globe valves, and check valves designed for chemical, petrochemical, and marine applications.

The supplier’s profile indicates a harbor trust tier, which suggests a verified business presence but limited transactional history on the platform. No response rate or average response time data is available, so buyers should expect to initiate contact directly for technical inquiries or custom configurations. The company does not list certifications or third-party accreditations in its profile, so buyers are advised to request compliance documentation for critical applications.
