Swagelok® Needle and Metering Valves
Swagelok needle valve and metering valves allow for precise flow control in a wide range of applications.
Needle Valves | Provide reliable flow control using a variety of stem designs, flow patterns, materials, and end connections
Metering Valves | Provide the ability to make fine adjustments to system flow across pressures and flow rates
Swagelok needle valves are available in a variety of configurations to allow users to find options that suit their performance needs and system designs. These needle valves provide reliable operation from basic, low-pressure instrumentation applications to corrosive, high-temperature, high-pressure applications. Swagelok needle valves are available with flow coefficients ranging from 0.12 to 2.4. They are also available with low emissions (Low-E) certification per API 624.
Swagelok metering valves are also available in a variety of configurations, are suitable for low- and high-pressure use, and can deliver accurate flow rate control in analytical, instrumentation, and research applications. They provide fine adjustments in applications demanding precise levels of flow, delivering flow coefficients from 0.004 to 0.16. Various handle options for metering valves allow for repeatable flow adjustments, enhanced control for setting flows, or flow setting adjustment with a screwdriver in low-pressure applications.
