What job is the valve operator actually doing?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">The operator converts a human or electrical command into valve shift. Manual levers suit local control and simple stations. Solenoids suit remote panels, PLC logic and repeated automatic cycles.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-2-which-plant-or-machine-constraints-decide-first\">Part 2. Which plant or machine constraints decide first?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Ask whether an operator can reach the valve safely, whether the machine must sequence automatically, and whether an electrical supply is already defined. Hazardous access, cab control and maintenance overrides often change the answer.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-3-how-should-electrical-and-override-details-be-captured\">Part 3.

When does a hybrid arrangement belong on the RFQ?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Some machines need solenoid control for production and a manual override for setup or rescue.
