PJ-4000C optimized electric sealing dispensing valve targets small-size folding boxes including lipstick cartons, medicine blister outer boxes and snack mini gift boxes, featuring an exclusive anti-drip nozzle structure to eliminate residual glue dripping during line stop intervals. Traditional glue guns leave glue drops contaminating printed surfaces, generating high reject rates for delicate small packaging;
PJ-4000C solves this core appearance defect.Precision electromagnetic instant cut-off control stops glue output within 0.01s after signal cutoff, with a built-in tiny back-suction mechanism retracting residual glue inside the nozzle. Miniature nozzle diameter supports ultra-narrow 2mm thin glue lines, ideal for small carton narrow flap bonding without glue overflow onto printed graphics.Low-power electric drive operates stably at medium line speeds from 80–220m/min, compatible with Q-series compact controllers and HB6 medium-pressure glue pumps. The lightweight 2.8kg valve body supports flexible top or side mounting on narrow folder gluer glue stations for small cosmetic box production lines.Main users are daily chemical mini packaging factories, small pharmaceutical printing workshops and food mini carton manufacturers.
PJ-4000C drastically reduces carton surface glue pollution rejects, unifies delicate small box bonding quality and lowers glue waste from dripping compared with standard glue valves.
