Product Introduction
Product Description:
The KQ PJ-4000C Electric Automatic Sealing Dispenser Valve is an electrically control valve with automatic nozzle seal. The seal cover can be activated with electrical signal. This feature is crucial for highly automated machinery where the dispenser valve is mounted on difficult to access area.
Feature:
- Electrical control valve, work in high speed and high precision
Core Advantages:
- Electric automatic nozzle sealing design (core highlight) Equipped with electric signal-driven automatic seal cover, the nozzle fully closes once gluing stops. It effectively stops cold glue outflow, stringing and nozzle curing blockage, eliminating frequent manual flushing for valves installed in hard-to-reach narrow machine positions. Operators save massive cleaning downtime for continuous shift production.
- Ultra-high speed & stable precision dispensing Max switching frequency reaches 500Hz, matching ultra-high-speed carton lines up to 300m/min. It delivers consistent dot and line glue patterns without broken trails or uneven glue volume, lowering defective packaging rates for mass automated production.
- Gravity-independent high-pressure mounting Supported by 32-bar maximum working pressure, this valve is free of gravity limits. It can be installed horizontally, vertically or upside down to fit compact, hidden mounting slots inside flexo folder gluers and automatic carton equipment, a critical strength for complex multi-track layout.
- Wide cold glue compatibility Works perfectly with water-based white latex cold glue with viscosity up to 5000mPas, compatible with all standard paper packaging adhesives. 12V low-voltage electric drive ensures safe, stable long-hour operation without circuit overload risks.
- Compact integrated stainless steel structure The whole valve body adopts corrosion-resistant stainless steel, suitable for humid workshop environments. Standard interchangeable nozzles support gluing from tiny food cartons to heavy double-wall corrugated cases, with unified spare parts compatible with PJ-4000 series for easy stock management.
- Fully automated linkage capability The auto-sealing function links seamlessly with packaging machine PLC signals. No manual interve
Main Applications:
Hard-to-reach installation equipment scenarios
High-speed flexo printer slotter folder gluers, multi-layer automatic carton pasting machines, narrow-frame post-press folding equipment, and compact paper bag making lines where valves cannot be manually accessed for daily cleaning.
Corrugated & logistics packaging
High-speed production of single/double-wall corrugated shipping boxes, multi-flap crash-lock cartons, large logistics outer cases requiring long continuous running without frequent shutdown cleaning.
Food & premium rigid packaging
Mass production of snack cartons, pharmaceutical folding boxes, cosmetic gift boxes, wine & tea rigid boxes, window patch printed cartons; continuous batch production with short intermittent stops between product batches.
Matching Cold Glue Systems
Fully compatible with KQ-PJ23, KPM-PJ-V24 (HB6 pump) and KPM-PJ-V28 (HB9 high-flow pump), expandable as multi-channel synchronous gluing heads for all KQ cold glue dispensing equipment.
