Specialized vacuum valves for solar panel manufacturing tools

VAT has made considerable investments in the development of a wide range of transfer valves tailored to the requirements of the most advanced solar panel manufacturing tools. One of the newest developments is the roll coater transfer valve. Due to the linear motion 3D sealing technology it is possible to clamp and seal the web (metal or plastic) without any damage.
