The Swagelok SS-12NBSW8P-SC11 Stainless Steel Needle Valve is a severe-service, union-bonnet throttle valve designed for precise flow control in instrumentation lines, offering a 2.4 Cv (flow coefficient) and 1/2-inch Swagelok tube fittings that permit compact, leak-tight installation in tight spaces. In Swagelok's N Series construction, the valve body and bonnet are made from 316 stainless steel for corrosion resistance, while the stem is alloy 400, a combination that helps resist galling and wear in demanding gas and liquid service. The SS-12NBSW8P-SC11 variant ships with Special Cleaning and Packaging SC-11, ensuring traceable cleanliness and suitability for critical applications where fluid purity and integrity matter, and it is designed for reliable operation in high-temperature or corrosive environments. End connections are Swagelok tube fittings at 1/2 inch, and the union-bonnet design supports straightforward disassembly for maintenance, calibration, or replacement without disturbing adjacent piping, making it well suited for high-precision instrumentation in chemical processing, petrochemical, and related industries.
