Product Overview
This two-way manual valve (1 in, 1 out) is a manual switch valve specially developed for ink supply systems. It is widely used for controlling the ink flow of printing equipment such as inkjet printers, UV flatbed printers, photo machines, and digital printing devices. The product adopts a 1-in-1-out two-way structure design, which achieves precise opening and cutting of the ink pipeline through manual operation.
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
Water based ink - reliable sealing, no risk of leakage
UV Ink - Polymer resistant medium, non clogging, non aging
Weak solvent ink - suitable for various weak solvent printing equipment
Oil ink - suitable for high viscosity ink pipelines
Core Features
1. One in one out two-way design
The standard 1-in-1-out two-way structure is designed specifically for the on/off control of single ink pipelines, with easy installation and intuitive operation.
2. Corrosion resistant material
The valve body is made of chemically resistant materials, which can withstand long-term exposure to corrosive media such as solvent based ink and UV ink without aging or leakage, ensuring the service life of the equipment.
3. Reliable sealing
Adopting high-quality sealing structure ensures no dripping or backflow after ink cutting, effectively preventing nozzle clogging and ink waste.
4. Manual operation, simple and reliable
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.
