Vannes à pointeau et de réglage fin Swagelok®
Les différentes conceptions des vannes à pointeau – à chapeau intégral ou à chapeau union – ainsi que le choix importants d’options – modèles de tiges, types d’écoulement, matériaux, raccordements – permettent de réguler le débit avec précision dans une large gamme d’applications. Les vannes de réglage fin offrent la possibilité d’ajuster précisément le débit dans des applications qui mettent en œuvre des pressions faibles ou élevées et des débits faibles, moyens ou élevés.
View Needle and Metering ValvesSwagelok 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.
