Swagelok SS-0RS2-W20 Needle Valve

Swagelok SS-0RS2-W20 Needle Valve is a stainless steel, integral-bonnet valve designed for precise, leak-tight flow control in instrumentation and process piping. The design incorporates a regulating stem for fine adjustment and a compact, robust body suitable for challenging environments, with 1/8 in Swagelok tube fitting end connections that integrate easily into Swagelok systems. The W20 designation indicates a hydrostatic test configuration in Swagelok documentation, typically reflecting testing at 1.5 times the maximum working pressure to verify integrity. This valve is intended for applications requiring dependable metering and shut-off in gas or liquid services, including analytical instrumentation, sampling lines, and high-purity or corrosive environments where stainless steel construction helps resist contamination and corrosion. When installed as part of a Swagelok flow-control system, SS-0RS2-W20 offers repeatable throttling and steady performance across a range of pressures, making it a suitable choice for precision flow management in laboratory, chemical processing, and industrial instrumentation setups.
