Which seal is it?<\/strong><\/p>\n<p>\n  Identify the location and function of the part. A pilot seal, main-valve<br \/>\n  sealing element and connection seal should not automatically inherit the<br \/>\n  same maintenance rule.\n<\/p>\n<p><strong>2. Is the part and material correct?<\/strong><\/p>\n<p>\n  Pilot-operated valve families can use different soft-goods materials for<br \/>\n  different configurations and services. A replacement part should match<br \/>\n  the approved valve configuration rather than merely having the same<br \/>\n  apparent dimensions.\n<\/p>\n<p>\n  For deeper material-selection context, see the<br \/>\n  <a href=\"https:\/\/zobai.com\/ar\/blog\/safety-valve-material-selection-guide\/\"><br \/>\n    \u062f\u0644\u064a\u0644 \u0627\u062e\u062a\u064a\u0627\u0631 \u0645\u0648\u0627\u062f \u0635\u0645\u0627\u0645\u0627\u062a \u0627\u0644\u0623\u0645\u0627\u0646<br \/>\n  <\/a>.\n<\/p>\n<p><strong>3. Is its condition acceptable?<\/strong><\/p>\n<p>\n  Inspect the component for the forms of damage or deterioration addressed<br \/>\n  by the applicable manufacturer procedure. Appearance is useful evidence<br \/>\n  of physical condition, but it does not establish material identity or<br \/>\n  service compatibility.\n<\/p>\n<p><strong>4. Does the applicable procedure permit reuse?<\/strong><\/p>\n<p>\n  This is separate from appearance. If the manufacturer procedure requires<br \/>\n  replacement of that component during the applicable service operation, an<br \/>\n  apparently intact seal is not evidence for ignoring the requirement.\n<\/p>\n<p>\n  The same distinction matters during procurement.
