There\u2019s never any question about whether or not the valve is open&nbsp;because you can tell at a glance. If the male and female valves are connected, the&nbsp;flow path is open. If they aren\u2019t, it\u2019s closed. Open-position valves also available.*<\/p>\n\n\n\n<p>*&nbsp;Open-position option available to prevent vacuum\/pressure from being trapped by the valve when desired (e.g., when using a vacuum\/pressure gauge). High flow facilitates use with canister-cleaning ovens.<\/p>\n\n\n\n<p><strong>Which RAVEqc Quick-Connect Air Valves Do I Need?<\/strong><\/p>\n\n\n\n<p>Use these guidelines to select the perfect RAVEqc quick-connect air valve for your application!<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Every RAVEqc quick-connect air valve has two halves (valve end and fitting end). Match each end to the&nbsp;opposite gender valve or fitting. For fittings, also be sure to match the connection dimension.<br><em>Examples:<\/em><ul><li>To connect directly to a Restek air can with a tube stub&nbsp;\u00bc&#8221; female compression fitting, use a bracket and any&nbsp;RAVEqc air valve with a \u00bc\u201d male compression fitting.<\/li><\/ul><img loading=\"lazy\" decoding=\"async\" width=\"1800\" height=\"549\"

class=\"wp-block-list\">\n<li>For tube end fittings, choose length based on the clearances you need for installation.<\/li>\n\n\n\n<li>For reactive compounds, use Siltek-treated valves for a highly inert sample path.<\/li>\n\n\n\n<li>Male valves are less expensive than female valves, so use them on your most numerous devices (e.g., air canisters,&nbsp;not cleaning
