History of Vacuum Research Corporation VRC traces its

History of Vacuum Research Corporation (VRC) traces its history back almost 60 years. VRC was one of the pioneer companies in the high vacuum industry when we introduced our vacuum gate valves in 1953 and our product development efforts have never stopped. Many of the products we offer today such as our active Pirani gauge and full opening Throttle. Master™ valve are truly state of the art technology and more importantly everything we ship is state of the art in quality and reliability. VRC’s key personnel possess over 125 years of vacuum industry experience. Allow us to help you enable your vacuum process.

VRC Milestones 1953 Aluminum gate valve production began in northern California. Virtually every part was made by permanent mold casting. 1987 Valve manufacturing operations moved to Pittsburgh, PA. 1988 Vacuum gauge production begins in Newport News, VA. 1995 Start of redesign of valve product line to replace castings with extrusions to eliminate real and virtual leaks due to casting porosity.

VRC Milestones 2005 Elimination of castings is complete and no valve shipped in 2005 was in the product line 1995. 2006 Added Solid Works to Auto-CAD. VRC can now provide 3 -D STEP file models of all valves to system designers. 2007 Introduced the 50 m. Torr to 1000 Torr Diaphragm Manometer. 2008 Introduced the 10 -5 Torr to 1000 Torr Super Wide Range Diaphragm Manometer.

VRC Milestones 2009 An article appearing in Vacuum Technology & Coating acknowledges the superior aluminum welding capabilities of Vacuum Research Corporation. 2009 Introduction of our Active Pirani Gauge that can replace any Pirani or Thermocouple gauge.
