Manufacturing technologies such as semiconductors, displays and solar cells require an ultra-clean, ultra-high-vacuum environment. VAT has earned the trust of organizations seeking mission-critical components for manufacturing, research, and development under the most rigorous conditions.  

Our customers know that with our innovation, engineering excellence, and  by listening, we’ll meet and anticipate their needs in the world’s most challenging and rapidly evolving markets. 
By continually earning and re-earning this trust, we’ve become the world leader in vacuum valves and related technologies. Here are six reasons why VAT is trusted by the very best.

We are close to our customers worldwide.

Headquartered in Switzerland, we have Sales and Service representations in 29 countries, R&D sites in Switzerland, the US, and Malaysia. Our major manufacturing facilities are in Switzerland, Malaysia and Romania – staffed by around 3,000 people passionate about their jobs and keeping our customers at the cutting edge.

We custom-engineer our products and services.

Our engineers work closely with our customers to develop solutions to meet their needs and challenges. No matter the application or environment, our valves can help maintain constant conditions and replicability at scale. Their first point of contact is an engineer, this way we can precisely meet our customers’ needs, no compromise.

We are committed to ultra-clean production.

This helps create the environments needed to research, develop, and manufacture semiconductors, displays and solar cells, optics and lasers, medical technology, space and high-energy applications. Ultra-clean production means also, that our products are not generating new particles or contaminants – which could be critical at the nano-meter levels we are working at.

We offer the world’s broadest portfolio of valve technology and related products.

Our offering ranges from Vacuum Valves, Gas Inlet Valves, and Multi-Valve Modules to Motion Vomponents and Edge-Welded Metal Bellows.

We are also geared up for retrofitting, refurbishment, servicing and upgrading.

This enables us to respond flexibly and efficiently to our customers’ needs, whatever their starting point.

We are a long-established company with a stock exchange listing.

In the business for 60 years, we have been listed on the Swiss Stock Exchange since 2016 and report under international standards for transparency and accountability.
