Mechanical Engineering – Cooling

Valves specifically for use in plastics processing machinery have to be both efficient and reliable. We have many years of accumulated experience and know-how encompassing standard products and custom solutions for a controlling a wide variety of process aspects such as cooling. 
Compressed air
Compressed air is the most important energy for the production process. It should be dry and clean. The compressor which transports the air to the machines sucks in ambient air. This can carry oil, water and contaminants. In order to clean the air, it must be guided through an absorption tank, in which drying and cleaning processes take place. Here, solenoid valves are used.

Compressors must be able to start up easily at any time. The released start usually occurs through an indirectly actuated diaphragm valve in the normally open function. A few seconds after the start of the compressors, the magnet is energised via a time relay, the valve is closed and the compressor then conveys into the compressed air system.

Print & Paper
Our diaphragm valves are mainly used on the station and delivery. At the station they help to position the paper at the printer and feed it. The printed paper is then placed down again and loosened in the stack. Solenoid valves control the air supply which is required for this process.

Another application is the control of the colour change when printing. Newspapers are printed in eight different colours. In case of a format change, the user must replace all colours in each cylinder and rinse these out. In a new system, changing the colours is controlled automatically and a wash is integrated. Solenoid valves control this procedure.

Plant Construction
In plant engineering our valves help to control processes. Depending on the application we develop the right product to work with very different media like water, air or ammonia.
For example, our valves are used in foil rolling mills. They control roll cooling and thus must impress with short opening and closing times as well as long and precise repetitions.
