2507 Super Duplex Ball Valves, ASTM A890 Grade 5A Gate Valve and UNS S32750 Check Valve Manufacturer, Supplier, and Exporters in India

Mcneil Instruments’ Super Duplex Valves feature a duplex microstructure, offering numerous advantages for prolonged service life. In comparison to commonly utilized carbon steels or stainless steel grades, Mcneil Instruments’ Super Duplex Stainless Steel Ball Valves exhibit enhanced tensile strength, superior corrosion resistance, and the capability to endure elevated temperatures. An essential attribute is their higher PREN value, rendering them highly resistant to pitting in corrosive surroundings.

Mcneil Instruments offers a wide range of F53/F55 Super Duplex Instrumentation Valves, manufactured in 1.4410 and 1.4501 grades, available in various configurations and sizes. These Super Duplex Stainless Steel Instrumentation Valves serve as essential fittings within piping systems, capable of both isolating and regulating media flow. Operating with a rotating disk closure mechanism, commonly known as a sluice valve, these valves control the flow by lifting a barrier from the media pathway, making them ideal for diverse hydraulic applications.
