Product Overview
The 7801-C127 Type Secondary Ink Cartridge Manual Valve Assembly is a high-performance integrated manual valve assembly developed specifically for Onepass inkjet printing systems and multi nozzle industrial printing equipment. The product integrates 7 independent manual valves and adopts a 1-control and 1-precision control mode. It is equipped with 7 independent outlets at the bottom to achieve independent on/off control of multiple ink pipelines.
This product is designed specifically for Onepass high-speed inkjet printing scenarios and can meet the complex control requirements of multi-color and multi nozzle ink supply systems. It is the core component of ink path management for industrial grade digital printing equipment.
Applicable Medium
This product has excellent medium compatibility and is suitable for the following types of inks and fluids:
Solvent ink - corrosion-resistant design, long-term contact without swelling or aging
Water based ink - reliable sealing, zero leakage guarantee
UV Ink - Polymer resistant medium, non clogging, non curing adhesive
Weak solvent ink - suitable for various weak solvent printing equipment
Oil ink - suitable for high viscosity ink pipelines
Core Features
1. 7-way independent 1 control 1 design
Integrate 7 independent manual valves, each corresponding to 1 independent outlet, achieving 1 control and 1 precise control. Each channel can be independently opened or closed without interfering with each other, meeting the flexible control requirements of multi-color and multi nozzle ink supply systems.
2. Bottom 7 outlet layout
Seven independent outlets are configured at the bottom, optimizing the pipeline direction for direct connection with nozzles or downstream equipment, reducing ink path bending and pressure loss, and improving ink supply efficiency.
3. Optimized specifically for the Onepass system
Designed to meet the continuous and high flow ink supply requirements of Onepass high-speed inkjet printing system, ensuring ink supply stability and consistency during long-term high-speed printing.
4. Corrosion resistant materials
The valve body and flow channel are made of chemically resistant materials, which prevent aging and leakage when exposed to corrosive media such as solvent based ink and UV ink for a long time, ensuring the service life of the equipment.
5. Reliable sealing, zero leakage
Adopting high-quality sealing structure and precision machining technology, it ensures that there is no dripping, backflow, or ink leakage after the valve is cut off, effectively preventing nozzle blockage and ink waste.
6. Manual operation, simple and reliable
Pure manual mechanical control, no need for power supply, simple and intuitive operation, especially suitable for equipment maintenance, nozzle cleaning, ink path switching and other scenarios.
