The DXGF40-40-12 Semi-Electronic Valve Carbonated Beverage Filling Machine is designed for automatic PET bottle filling of carbonated soft drinks, sparkling water, soda, cola, and other carbonated beverages.
The machine integrates 40 bottle rinsing stations, 40 semi-electronic filling valves, and 12 capping heads into one automatic rotary system. It combines isobaric filling technology with PLC-controlled valve operation to improve filling consistency, pressure management, and production stability.
Compared with conventional mechanical filling valves, the semi-electronic valve configuration provides more flexible control of filling sequences and valve actuation. This helps reduce unnecessary foaming, maintain carbonation, and improve repeatability during continuous production.
With a reference production capacity of 15,000–18,000 bottles per hour, depending on bottle size and operating conditions, the DXGF40-40-12 is suitable for medium-to-large carbonated beverage manufacturing plants.
Advanced Semi-Electronic Valve Carbonated Filling Technology
The DXGF40-40-12 combines automatic valve actuation with isobaric filling technology for carbonated beverages.
During the filling process, the machine manages CO₂ pressure equalization, beverage filling, and controlled pressure release. Pneumatically actuated filling valves respond to PLC control signals, allowing the system to coordinate valve operations during continuous production.
This configuration provides more flexible control over filling timing than a purely mechanical valve system.
The actual filling performance depends on valve design, pressure stability, beverage temperature, carbonation level, and machine settings.

How Does the DXGF40-40-12 Filling Machine Work?
The DXGF40-40-12 operates through three coordinated sections: bottle rinsing, counter-pressure filling, and automatic capping.
Bottle Rinsing
Empty PET bottles enter the machine through the infeed conveyor and bottle-handling system.
The 40-station rinsing section positions and rinses the bottles before transferring them to the filling carousel.
The rinsing configuration can be selected according to the required hygiene standard and production conditions.
CO₂ Pressure Equalization
After the rinsing stage, bottles are transferred to the filling section.
Each bottle is positioned against a filling valve. The filling system introduces CO₂ to establish suitable internal pressure before beverage filling begins.
This pressure equalization process reduces sudden CO₂ breakout when the carbonated beverage enters the bottle.
Semi-Electronic Valve Filling
The PLC coordinates valve actuation during the filling cycle.
Compressed air operates the pneumatic valve components, while control signals manage the required filling sequence.
The carbonated beverage enters under controlled pressure conditions.
After reaching the required filling level, the machine completes the filling process and performs controlled pressure release.
This helps limit foam overflow before the bottle reaches the capping station.
Automatic Bottle Capping
The filled bottles enter the 12-head capping section.
The automatic cap feeding and capping system applies compatible plastic screw caps to the bottles.
The synchronized transfer arrangement minimizes delays between filling and sealing.
After capping, the bottles leave the machine through the discharge conveyor and continue to downstream inspection, labeling, and packaging.

Semi-Electronic Valve vs. Mechanical Filling Valve
The filling valve plays an important role in carbonated beverage production because it controls the product transfer process and affects filling stability.
Traditional mechanical isobaric valves generally rely on mechanical actuation sequences, while semi-electronic valves use electronic control signals together with pneumatic components.
| Feature | Mechanical Filling Valve | Semi-Electronic Filling Valve |
| Valve Actuation | Mechanical Control | PLC-Controlled Pneumatic Actuation |
| Filling Sequence | Mainly Mechanical | Electronically Coordinated |
| Timing Adjustment | Mechanical Adjustment | Control-Parameter Adjustment |
| Operating Flexibility | Standard | Greater Control Flexibility |
| Control Integration | Basic | PLC-Based |
| Maintenance Focus | Mechanical Components | Pneumatic and Control Components |
| Typical Application | Standard CSD Filling | Automated CSD Production |
A semi-electronic valve should not be confused with a fully electronic flowmeter filling valve.
The term semi-electronic refers to electronic control of selected filling operations. It does not automatically mean that each filling valve uses an electronic flowmeter for volumetric measurement.

The treatment configuration is designed according to raw water quality and the required product specifications. Automated monitoring helps maintain stable water treatment performance and provides a reliable water supply for syrup preparation and beverage mixing.
Syrup Preparation and Mixing System
The syrup preparation system ensures accurate ingredient mixing and consistent beverage formulation. Sugar is dissolved and filtered before being transferred to sanitary mixing tanks, where it is combined with flavor concentrates and other ingredients.
Stainless steel tanks, sanitary pumps, and automated dosing controls help maintain consistent mixing ratios. The system can also incorporate CIP cleaning to support hygienic production and efficient recipe changeovers.
Prepared syrup is transferred to the beverage blending system for proportioning with treated water before carbonation.
Carbonation and Chilling System
The carbonation and chilling system controls beverage temperature, CO₂ concentration, and mixing conditions before filling.
A beverage chiller typically reduces the product temperature to approximately 2–4°C, depending on the formulation and carbonation requirements. Lower temperatures improve CO₂ solubility and help maintain stable carbonation during production.
The carbonation system mixes treated water and syrup at the required ratio before introducing food-grade CO₂ under controlled pressure. PLC automation monitors temperature, pressure, and flow to maintain consistent beverage quality.

After labeling and inspection, finished bottles enter the secondary packaging section for automatic grouping and packing.
The carbonated beverage production line can be equipped with PE film shrink wrapping machines, carton packing machines, or other packaging systems according to market requirements.
Shrink packaging can group bottles into packs of 6, 12, or 24, depending on bottle dimensions and packaging design. Carton packaging provides additional protection during storage and transportation.
Automatic packaging equipment reduces manual handling and helps maintain continuous production from filling to finished products.
Conveyor and Automation Control System
The conveyor system connects the main equipment into a complete automatic carbonated drink filling line, maintaining coordinated bottle movement throughout production.
Air conveyors transfer empty PET bottles from the blowing machine to the filling section, while stainless steel chain conveyors transport filled bottles through labeling, inspection, and packaging.
