VAT Vakuumventile AG makes vacuum valves, multi-valve modules, edge-welded bellows, and motion components for semiconductor, display, solar, research, and medical equipment makers.
VAT Vakuumventile AG designs and supplies high-performance vacuum valves, multi-valve modules, edge-welded bellows, and related motion and vacuum components used by manufacturers of electronics and advanced technologies. The product range spans high vacuum through ultra-high and extreme ultra-high vacuum regimes, serving semiconductor production, display manufacturing, solar technology, scientific research, and medical and pharmaceutical applications. Headquartered in Haag, Switzerland, the company employs more than 3,200 people and operates manufacturing sites in Switzerland, Malaysia, and Romania, supported by global sales and service hubs.
For engineers working on mechanisms that must operate under vacuum, the hardware constraints are the interesting part. Edge-welded bellows provide the sealing and motion interface that lets actuators translate or rotate while preserving vacuum integrity, and motion and vacuum components in the portfolio are specified for demanding vacuum manufacturing processes. Multi-valve modules integrate several valve functions into a single assembly, reducing the interfaces that process equipment builders have to design, seal, and qualify themselves. Valve performance is characterized against the pressure range a given tool operates in, from high vacuum up to extreme ultra-high vacuum.
Alongside new hardware, the company supplies spare parts, repairs, refurbishment, upgrades, and retrofit services, which means lifecycle engineering - keeping legacy vacuum systems in production and extending their service life - is part of the work rather than an afterthought. Engineering emphasis is placed on reliable product design and close collaboration with customers on application requirements. Teams are international and distributed across the company's manufacturing countries.
