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 ThrottleMaster™ 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.
Aluminum gate valve production began in northern California. Virtually every part was made by permanent mold casting.
Valve manufacturing operations moved to Pittsburgh, PA.
Vacuum gauge production begins in Newport News, VA.
Start of redesign of valve product line to replace castings with extrusions to eliminate real and virtual leaks due to casting porosity.
Elimination of castings is complete and no valve shipped in 2005 was in the product line 1995.
Added Solid Works to Auto-CAD. VRC can now provide 3-D STEP file models of all valves to system designers.
Introduced the 50 mTorr to 1000 Torr Diaphragm Manometer.
Introduced the 10 -5 Torr to 1000 Torr Super Wide Range Diaphragm Manometer.
An article appearing in Vacuum Technology & Coating acknowledges the superior aluminum welding capabilities of Vacuum Research Corporation.
Introduction of our Active Pirani Gauge that can replace any Pirani or Thermocouple gauge.
