The YCT-GZ Series Automatic Gravity Flow Liquid Filling Machine is built around the most reliable liquid filling principle: gravity. By positioning the product tank above the filling heads and using timed gravity-fed flow valves to control fill volume, the series delivers consistent fills for thin, free-flowing liquids without pumps, servo drives, or pistons — fewer moving parts mean lower maintenance costs and more reliable long-term operation.
Six configurations — 6, 8, 10, 12, 16, and 20 heads — scale from 1200 pcs/h to 6000 pcs/h. Fill accuracy of ±1% is maintained through timed valve control, calibrated on the HMI without mechanical changes.
All product-contact surfaces are food-grade stainless steel. Anti-drip valves prevent trailing liquid after each fill cycle. The series integrates inline with Yucheng capping, labeling, and conveying equipment for a complete turnkey line.
Gravity Flow Reliability — No pump motors, servo actuators, or pistons in the product flow path. Gravity filling offers fewer failure points and lower long-term maintenance costs than mechanically driven alternatives.
6 Scale Configurations — Available in 6, 8, 10, 12, 16, and 20-head models, scaling from 1200 to 6000 pcs/h with the same control platform across all sizes.
Low Power Consumption — Total power from 1.0 KW (6-head) to 3.0 KW (20-head) — a fraction of pump-based or servo-driven filling systems at equivalent throughput.
±1% Fill Accuracy — Timed gravity valve control delivers consistent ±1% fill accuracy. Fill time is calibrated per product and adjusted digitally on the HMI without mechanical intervention.
Food-Grade Stainless Steel — Tanks, pipes, valves, and all product-contact surfaces meet food, beverage, and pharmaceutical hygiene standards.
Anti-Drip Valve Design — Spring-return anti-drip valves close cleanly at the end of every fill cycle, preventing liquid trails and keeping the filling zone clean.
Easy Cleaning & Maintenance — The gravity tank and flow lines support CIP flushing or manual washdown between product types.
Production Line Ready — Conveyor speed, infeed, and outfeed heights are configurable for integration with capping, sealing, and labeling equipment downstream.

The YCT-GZ gravity flow series is optimized for thin, free-flowing liquids:
Beverages & Drinking Water — Bottled water, mineral water, juice, sports drinks, and ready-to-drink beverages
Food Condiments — Soy sauce, vinegar, cooking wine, and thin liquid seasonings
Daily Chemicals & Household — Liquid detergent, rinse aid, window cleaner, and liquid disinfectant
Alcohol & Spirits — Spirits, wine, beer, and other alcohol products where non-pressurized filling is preferred
Agricultural & Industrial Chemicals — Herbicides, pesticides, and thin chemical solutions requiring accurate dosing
Pharmaceutical Liquids — Oral rinses, liquid wound care solutions, and thin supplement preparations
Matched to Thin Liquid Applications — Yucheng specifies gravity filling for thin liquids rather than over-engineering with pumps or servo drives, delivering the right accuracy at the lowest total cost of ownership.
Six Head Configurations — Machine sizes from 6 to 20 heads give buyers a precisely matched capacity without over-investing or being constrained at peak production.
Pre-Shipment Fill Calibration — Each machine is calibrated to your fill volume and tested at production speed before dispatch. Valve timing parameters are documented for easy replication after cleaning.
OEM and Integration Support — Yucheng customizes tank capacity, head pitch, conveyor specs, and machine height to match your line. Complete turnkey lines including cappers, labelers, and conveyors are also available.
Responsive Technical Support — Operation manuals, maintenance guides, and remote video support provided. Spare valves and wear parts are stocked for fast dispatch.
Q: What liquid viscosity range is suitable for gravity filling?
A: Gravity flow suits thin liquids below approximately 200 cP — water, juice, vinegar, and alcohol. Thicker products need a piston or pump filler. Share your product viscosity and we will recommend the right method.
Q: How is fill volume adjusted between products or container sizes?
A: Fill volume is controlled by valve open time, set on the HMI. Volume changes take a few minutes with no mechanical changes. Container size changes may require guide rail adjustment.
Q: How do I choose between the 6-head and 20-head models?
A: For 1200–1800 pcs/h, the 6-head is appropriate; for 5000–6000 pcs/h, the 20-head. Share your output target and container size and we will confirm the right model.
Q: Can the machine handle different bottle shapes and sizes?
A: Yes. Compatible with round, square, and rectangular bottles. Guide rails and head pitch are adjustable. Confirm your container range when ordering.
Q: What is the MOQ and lead time?
A: MOQ is 1 unit. Standard configurations ship in 10–15 business days; custom or non-standard requirements may extend to 20–25 business days. We confirm the timeline at order placement.
Q: Is the machine suitable for carbonated beverages?
A: No. The open fill process allows CO₂ to escape, causing foam and inconsistent fill levels. Carbonated products require a counterpressure system. Contact us to discuss the right equipment.
Q: Can I connect the YCT-GZ filling machine to downstream capping or labeling equipment?
A: Yes. The outfeed conveyor integrates with capping machines, foil sealers, and labelers. Yucheng manufactures all these types, so a matched line can be supplied from a single source.
The YCT-GZ gravity flow series gives you a reliable, low-maintenance, and energy-efficient filling foundation for thin liquid products — at any throughput level from 1200 to 6000 pcs/h. Tell us your fill volume, target output, product type, and container size and we will identify the right model and provide a detailed, competitive quotation.
