Intelligent solenoid valve, precise control: The built-in solenoid valve can achieve automatic/remote on-off of the ink path. Cooperating with system instructions, it can instantly cut off ink when shutting down, standby, or detecting faults, effectively preventing ink leakage and ink leakage, and protecting precision nozzles.
Dual chamber structure, bubble killer: The unique dual chamber design can efficiently separate and retain small bubbles in the ink, ensuring that the ink flowing to the nozzle is pure and bubble free, fundamentally eliminating problems such as printing breakage and oblique spraying caused by bubbles.
Transparent Acrylic, Clear at a Glance: Made of high transparency acrylic material, the ink level and ink state (bubbles, impurities) are clear at a glance, making it easy for daily maintenance and liquid level monitoring.
Water based ink specific compatibility: The material and design are fully optimized for the characteristics of water-based ink, ensuring long-term chemical compatibility, preventing corrosion and deterioration, and ensuring ink stability and bright printing colors.

1. The intelligent value of solenoid valves
Electromagnetic valve is the key to achieving "intelligent ink supply". It not only has a fast response speed, but can also be easily integrated into the fully automatic control system of the device. The implementation of automatic ink injection upon startup, automatic ink locking upon shutdown, and automatic protection in emergency situations greatly enhances the automation level and safety of the equipment.
2. Working principle and benefits of dual cavity structure
The ink first enters the first chamber for preliminary steady flow and pre defoaming; Subsequently, purer ink enters the second chamber through the bottom channel and is directly supplied to the nozzle. This physical isolation design greatly reduces the risk of bubbles entering the main circulation pipeline with ink, and is the physical basis for ensuring high yield.
3. Practical advantages of acrylic material
Compared to opaque materials, acrylic ink cartridges allow maintenance personnel to intuitively determine ink levels, observe ink circulation status, and detect abnormal bubbles or deposits without the need for complex tools, which is an important part of preventive maintenance.
4. Deep optimization of water-based ink circulation system
The circulation system requires continuous ink flow, and has extremely high requirements for the sealing, smoothness, and chemical stability of the ink cartridge. 7501-D20 has been specially optimized for the low viscosity and foaming characteristics of water-based ink in interface design, internal channel smoothness, and material selection, ensuring long-term stable operation in the circulation system.
