Product Overview
Swagelok needle valves are widely specified where predictable, repeatable flow control is required. The B-1RS4 is intended for fine metering rather than simple on-off service, using a needle-and-seat design to allow gradual, controlled adjustment. Brass construction and Swagelok tube fittings support integration into instrumentation panels, laboratory setups, and process sampling lines.
