WAGNER brings the newest version of colour change block that can be configured in a variety of ways and is suitable for various low-pressure applications in robotic and automation systems. Colour change blocks are essential for automatic liquid coating systems that require frequent colour switches when using multiple colours.

These applications are commonly used in industries such as wood and furniture coatings, particularly in flatbed machines where a wide colour range is needed. Additionally, automotive suppliers rely on them for coating both interior and exterior components with precision and efficiency.

Fast colour 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 colour changes are crucial. The WAGNER colour 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 colour changes. The configuration with two or more output channels offers further time savings: While the active colour is being applied, the other channel can be flushed and a second colour can be applied.

Great advantages, compactly installed

The WAGNER color change block stands out with its versatile configuration options. It can be designed as a compact double valve block with one output channel and up to 24 valves, a multi-channel block with up to 8 output and 24 input channels, or even as a 2K mixing block. Its modular design allows multiple valve blocks to be arranged in sequence, offering flexibility and customisation. With various connection options, such as gear pumps and material pressure regulators, it seamlessly adapts to diverse application 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 colour 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.
