Its installation and commissioning quality directly affect placement accuracy, air path stability, and even the overall production efficiency. Based on years of on-site operation experience, this article summarizes key points from pre-installation preparation to post-commissioning verification, helping you avoid common pitfalls and ensure stable operation of the solenoid valve.<\/div>\n<h2 class=\"heading-2 ace-line old-record-id-KyqnfdzVfdecHPcPfugcXWT0ndc\">I.

Secondary Calibration of Spare Part Parameters<\/h3>\n<div class=\"ace-line ace-line old-record-id-UHH1fOw1qd6Me6cvsDhc97JOn1b\">Never rely solely on &#8220;consistent model&#8221; to confirm usability. Conduct two key tests for new valves:<\/div>\n<ul class=\"list-bullet1\">\n<li class=\"ace-line ace-line old-record-id-ISQtfdNSedpdMac1GgScFZX0nVb\" data-list=\"bullet\">\n<div><strong>Coil resistance test<\/strong>: Use a multimeter to recheck. DC valves typically range from 10\u201330\u03a9, while AC valves are 50\u201380\u03a9.

Reverse connection leads to insufficient valve core suction. AC valves have no polarity, but ensure terminal crimping torque (0.8\u20131.2N\u00b7m) to prevent overheating from loose connections.<\/div>\n<\/li>\n<li class=\"ace-line ace-line old-record-id-ES61fkJtqdlvqvcxxtwccIAZnne\" data-list=\"bullet\">\n<div>For manifold-integrated solenoid valves, match the mounting torque to the machine model (e.g., 1.5N\u00b7m for Yamaha YSM series).
