KQ PJ-4100 Multi Nozzle Single Valve Dispenser offer the convenience of dispensing multiple lines of glue using a single valve. This is especially useful for application that requires pasting large area of product.
Due to high pressure supplied by pump, PJ-4000 can be mounted at any angle, irrespective of gravity.
Feature:
2-4 nozzle holes
line/dot pattern
Core Advantages:
Single valve with multi-nozzle integrated design
Equipped with 2–4 nozzle holes in one valve body, it outputs multiple parallel glue tracks simultaneously without installing several separate valves. It simplifies equipment layout, cuts installation space and reduces the total number of valves for multi-line gluing, lowering overall procurement and maintenance costs for packaging factories.
High-pressure gravity-independent mounting
Supported by 32-bar max working pressure, this dispenser works free of gravity restriction. It can be mounted horizontally, vertically or upside down to fit narrow internal frames of flexo folder gluers, solving layout limits for multi-side synchronous gluing on large cartons.
Ultra-high stable dispensing performance
It reaches a switching frequency of 500Hz and matches production line speeds up to 300 m/min. It delivers uniform glue volume across all nozzles without uneven glue output or broken lines during long-hour continuous operation, ideal for mass high-speed carton manufacturing.
Dual glue pattern compatibility
Supports continuous line gluing and intermittent dot gluing. Operators switch modes via the cold glue controller to satisfy wide-area lamination, edge sealing, tear strip pre-bonding and multi-point positioning bonding on different packaging substrates.
Wide glue material compatibility
Suitable for water-based cold white latex with viscosity up to 5000mPas, fully matching standard packaging cold glue used on corrugated board, coated art paper, kraft paper and rigid box materials. It adopts 12V low-voltage electric drive with safe and stable operation.
Compact all-in-one structure
Integrated multi-nozzle head minimizes the overall size of the dispensing unit. It requires fewer pipelines and fixing brackets compared with multiple single-nozzle valves, simplifying machine assembly and daily cleaning workflows.
Main Applications:
Corrugated & Logistics Packaging
Large-size double-wall corrugated shipping boxes, multi-flap heavy cartons, wide crash-lock bottom panels, full-width edge sealing for bulk logistics cases. The multi-parallel glue lines strengthen box structural stability during long-distance transportation.
Premium & Large-Area Paper Packaging
Rigid gift boxes, wine/tea cartons, large cosmetic packaging, full-surface window patch bonding, box-in-box inner lining lamination. Multiple glue tracks evenly cover large bonding areas to avoid hollow degumming.
Food & Paper Bag Manufacturing
Large food takeaway trays, multi-layer snack cartons, wide kraft paper bag bottom sealing, full-width side edge bonding for shopping paper pouches. Parallel glue lines boost tensile strength of bag bases.
Matching Equipment
Perfectly fitted on KQ-PJ23, KPM-PJ-V24 and KPM-PJ-V28 cold glue dispensing systems, compatible with high-speed flexo printer slotter folder gluers, standalone carton pasting machines and automatic paper bag production lines.

Q1: How many nozzle holes does PJ-4100 support?
A1: Standard design with 2 to 4 interchangeable nozzle holes to realize multi-line synchronous gluing in one single valve.
Q2: Can this valve be installed upside down or sideways?
A2: Yes. Max 32-bar high-pressure feeding eliminates gravity influence, supporting all-angle mounting to adapt complex machine internal structures.
Q3: What glue patterns can PJ-4100 produce?
A3: It supports two adjustable modes: continuous line gluing and intermittent dot gluing, controlled by the matched cold glue system controller.
Q4: What viscosity range of cold glue can it handle?
A4: Compatible with water-based packaging cold glue with maximum viscosity of 5000mPas; hot melt adhesive is not applicable for this valve.
Q5: What are the voltage and switching frequency parameters?
A5: Rated voltage is 12V, maximum switching frequency reaches 500Hz, suitable for production lines up to 300 m/min.
Q6: What production scenarios is PJ-4100 more suitable for than PJ-4000 single-nozzle valve?
A6: PJ-4100 targets products requiring wide-area bonding and multiple parallel glue tracks. It replaces multiple PJ-4000 valves to save installation space and cost.
Q7: Is PJ-4100 compatible with all KQ cold glue pumps?
A7: Fully matched with HB6 standard glue pump (for V24) and HB9 high-flow glue pump (for V28), as well as the supporting system of KQ-PJ23.
Q8: How to clean the multi-nozzle head to prevent clogging?
A8: Flush the whole valve body and each nozzle hole with clean water after daily shutdown. Disassemble the nozzle head for deep cleaning if the equipment stays idle over 24 hours.
Q9: Can I replace single nozzles separately when they wear out?
A9: Each nozzle hole adopts independent replaceable nozzle structure. Users only change worn single nozzles instead of the whole multi-nozzle assembly to cut spare parts cost.
Q10: What are the main consumable spare parts of PJ-4100?
A10: Replaceable single nozzles, internal sealing rings and valve needles. We supply complete spare parts kits for fast on-site replacement.
We are committed to excellence in everything we do and look forward to working with you!
