The cylindrical or tapered plug fits inside the body bore. As the plug rotates 90\u00b0, it redirects flow from fully open to fully closed.<\/p>\n\n\n\n<p>Machined plug geometry provides tight shutoff without flow restrictions. The plug connects to an upper stem that rotates it via a handle, gearbox, or automated actuator. Together, the moving plug and stem enable reliable throttling and shutoff.<\/p>\n\n\n\n<p><strong>Where lubrication factors in:<\/strong><\/p>\n\n\n\n<p>Surfaces between the plug and body can experience high friction during cycling. Periodic re-lubrication here and on seals reduces torque needs and ensures smooth action. This prevents excessive wear that allows leaks or makes valves hard to operate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_To_Lubricate_A_Plug_Valve\"><\/span><strong>How To Lubricate A Plug Valve?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Here\u2019s a step-by-step guide on how to grease a plug valve:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Identify lubrication points<\/li>\n<\/ol>\n\n\n\n<p>These include grease fittings on valve bonnets or stems, and plug seal surfaces. Some plugs feature hollow cavities to hold grease internally.<\/p>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li>Select compatible grease<\/li>\n<\/ol>\n\n\n\n<p>Use lithium or calcium thickened base greases rated for valve application temperatures. Avoid incompatible greases containing solvents or corrosive compounds.<\/p>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li>Add grease<\/li>\n<\/ol>\n\n\n\n<p>Apply grease gun to fittings. Remove plug seals first if present and lightly coat sealing surfaces with fresh grease before reinstalling. Replace seals if wear is evident.<\/p>\n\n\n\n<ol start=\"4\" class=\"wp-block-list\">\n<li>Cycle valve<\/li>\n<\/ol>\n\n\n\n<p>Turn the plug fully open to closed several times post greasing to evenly distribute lubricant. Extra cycling helps purge any trapped air pockets.<\/p>\n\n\n\n<ol start=\"5\" class=\"wp-block-list\">\n<li>Inspect operation<\/li>\n<\/ol>\n\n\n\n<p>Plug rotation should move smoothly without stick-slip or high effort. Tight shutoff without leakage should occur on both sides of plug in closed position.<\/p>\n\n\n\n<ol start=\"6\" class=\"wp-block-list\">\n<li>Document maintenance<\/li>\n<\/ol>\n\n\n\n<p>Note grease brand and amount used. If issues are discovered, record details to determine if future adjustments like seal replacement are needed.<\/p>\n\n\n\n\n  <style type='text\/css'>\n\t\t\t\/* \u6574\u4f53\u6837\u5f0f *\/\n\t\t\tfieldset.test {\n\t\t\t\tpadding: 10px;\n\t\t\t\tmargin: 10px;\n\t\t\t\twidth: 100%;\n\t\t\t}\n\t\t\tfieldset.test ul {\n\t\t\t\tlist-style-type: none;\n\t\t\t\tmargin: 8px 0 4px 0;\n\t\t\t\tmargin-top: -15px;\n\t\t\t}\n\t\t\tfieldset.test li {\n\t\t\t\tmargin-top: 12px !important;\n\t\t\t\tlist-style: none !important;\n\t\t\t}\n\t\t\t\/* \u526f\u6807\u9898\u6837\u5f0f *\/\n\t\t\tfieldset.test .faq-title2 h3 {\n\t\t\t\tfont-size: 16px !important;\n\t\t\t\tfont-weight: 800 !important;\n\t\t\t}\n\t\t\t\/* \u6b63\u6587\u6837\u5f0f *\/\n\t\t\tfieldset.test p {\n\t\t\t\tfont-size: 14px !important;\n\t\t\t\tline-height: 20px !important;\n\t\t\t}\n\t\t<\/style>\n  <fieldset class='test' style='border: #d70c19 solid 1px;'>\n  <legend style='padding: 5px 10px;'><H2 style='font-weight: 800;font-size: 36px;color: #d70c19;'>FAQ<\/H2><\/legend>\n  <ul>\n    <li>\n      <!-- \u526f\u6807\u98981 -->\n      <span class='faq-title2'>\n        <H3>How do you tell if a plug valve is open or closed?<\/H3>\n      <\/span>\n      <!-- \u6b63\u65871 -->\n      <p>Position indicators, handle alignment, and number of turns indicate open vs closed status.
