Stainless Steel Severe Service Union Bonnet Needle Valve, 2.4 Cv, 1/2 in. FNPT, Ball Stem, Grafoil Packing
Engineered for reliability in the most demanding environments, the Swagelok 2507-12NBF8-G-2507 combines the proven performance of our severe-service union-bonnet needle valve design with the superior strength and corrosion resistance of Super Duplex Alloy 2507.
Exceptional Strength & Durability – Alloy 2507 provides high tensile and yield strength with excellent resistance to stress-corrosion cracking and pitting, even in harsh offshore and chemical processing applications.
High Pressure Capability – Rated up to 6000 psi (413 bar) at room temperature, ensuring safe, leak-tight operation in critical systems.
Wide Temperature Range – Grafoil® packing ensures reliable sealing from –65 °F (–53 °C) up to 1200 °F (648 °C).
Optimized Flow Control – Precision ball-stem tip design delivers consistent shutoff, smooth operation, and a flow coefficient (Cv) optimized for high-performance applications.
Versatile Connections – ½ in. NPT female ends provide compatibility with a wide range of system designs.
