Color change blocks are indispensable if several colors are used in an automatic liquid coating system and therefore frequent color changes are necessary. Typical areas of application are coatings in the wood and furniture industry, for example in flatbed machines, where there are high demands on color variety. Or at automotive suppliers for the coating of interior and exterior components.
Fast color change & low consumption of flushing agent
Automated coating systems must be able to ensure high cycle rates. To keep interruptions to ongoing operations to a minimum, fast and reliable color changes are crucial. The WAGNER color change block makes a major contribution to this. The desired application medium is simply selected via the respective pneumatically controllable valve. The time required for flushing and the consumption of flushing agent are very low thanks to the dead space-free inner geometry of the block - this shortens the time required for color changes. The configuration with two or more output channels offers further time savings: While the active color is being applied, the other channel can be flushed and a second color can be applied.
Great advantages, compactly installed
In addition, the WAGNER color change block scores particularly well with its individual configuration options: For example, as a compact double valve block with one output channel and up to 24 valves, as a multi-channel block with up to 8 output and 24 input channels, or as a 2K mixing block. Thanks to the modular principle, with which several valve blocks can be flexibly arranged in a row, and many connection options (e.g. for gear pumps or material pressure regulators), it can be adapted to a wide variety of requirements. It offers significantly more flexibility than comparable products on the market. Depending on the material applied, needle or diaphragm valves can be installed to increase the service life even for abrasive materials. Thanks to its size and modular design, the color change block can be perfectly integrated into various automated systems, e.g. on a robot arm, in installations with linear axes or 2K systems. It is easily accessible if maintenance is required, such as a hose change. It is also very easy to replace valves or valve blocks and extend the color change block - without the need for special tools.
WAGNER offers its customers a special service in its own web shop WAGNER365: They can use an online configurator to put together the color change block themselves according to their needs and order it directly.
