Product Description Product DescriptionNAl-LOK brand was established in Shanghai in 2000, we focus on the production, research and development, salesof instrumentation valves, fittings, hose & tubing. The NH Series Needle Valve, constructed from UNS S32750 (Super Duplex Stainless Steel), is engineered for precision flow control in high-pressure, corrosive, and extreme environments. Designed for industries such as oil & gas, chemical processing, marine, and power generation, this valve ensures reliable performance under demanding conditions.Key Features & Functions:Superior Material PerformanceUNS S32750 (Super Duplex SS) offers exceptional strength (2x higher than standard 316SS), outstanding corrosion resistance (against chlorides, acids, and seawater), and excellent stress cracking resistance. Ideal for harsh media like H2S, brine, and high-temperature steam.Precision Flow RegulationThe tapered needle-shaped plunger allows fine-tuned, gradual flow adjustment, minimizing pressure drops and preventing sudden surges. Suitable for instrumentation, hydraulic systems, and metering applications.High-Pressure & Temperature ResilienceRated for PN40/ANSI 300 and beyond, with a temperature range of -40°C to 250°C (-40°F to 482°F). Robust construction ensures leak-proof operation even under cyclic loading.Bidirectional Sealing & Zero LeakageMetal-to-metal sealing (or optional PTFE seats) provides bubble-tight shutoff, complying with API 598/ISO 5208 standards. Bi-directional design accommodates flow from either port.Compact & Maintenance-FriendlyCompact body design saves space in piping systems. The integrated stem packing (Graphite/PTFE) reduces wear, while the smooth-threaded stem ensures effortless operation over long service life.Versatile ConfigurationsAvailable in swivel/flanged ends, extended bonnet (for cryogenic use), and actuated versions (pneumatic/electric) for remote control.
