UHV Ultra-high Vacuum Isolation Valves
Overview
UHV Ultra-high Vacuum Isolation Valves are lightweight and have a compact profile, enabling it to fit easily into vacuum systems where space is tight. MKS has optimized the welded stainless steel bellows stroke length to ensure a long cycle life while maintaining high conductance.
- NW25 - NW40
- Ultra-high vacuum system applications
- Metal bonnet seal limits outgassing and permeation for a lower base pressure
- Spring-to-close, air-to-open pneumatic valve

Features
TIG Fusion-welded body
Another standard feature is a TIG fusion-welded body made of high grade, corrosion resistant 304 stainless steel for significantly fewer entrapment areas, resulting in less contaminants. The body is available with a choice of bead blasted or electropolished finishes.
UHV Applications
The UHV Valve is a compact vacuum valve designed for use in ultra-high vacuum systems, for physical vapor deposition, high energy physics, mass spectrometry and other applications that require an ultraclean environment.
