Swagelok SS-1RS8 Needle Valve Stainless Integral Bonnet

Swagelok SS-1RS8 is a stainless steel integral-bonnet needle valve with a straight-through flow path and a regulating stem, designed for precise throttling in 1/2 in Swagelok tube systems. It uses Swagelok 1/2 in tube fittings on both ends, enabling secure, leak-tight connections in tight spaces. The valve body is stainless steel, with an integral bonnet to minimize seal interfaces. It provides a Cv of 0.73, enabling fine control of gas or liquid flow at instrumentation pressures. This straight-pattern valve is suitable for instrumentation lines, sampling connections, and other flow-control points that run 1/2 in Swagelok tubing. The regulating stem allows adjustable, repeatable flow settings for accurate regulation in process control loops.
