Vacuum Research Corporation (VRC)
was a pioneer in the high vacuum business when its first patent was issued in 1954. More patents followed, and the innovation is continuing at our headquarters in Pittsburgh, Pennsylvania. Here are a few highlights of our last 60 years.
Aluminum gate valve production began in northern California. Virtually every part was made by casting.
Patented the first gate valve to provide 100% unobstructed flow and a rotary rather than sliding vacuum seal. No scuffing of the gate seal when opening or closing by using a 4 bar linkage. (Patent #2,850,260)
Patented remote control of the rotary actuator gate valve with pneumatic cylinder. (Patent #3,141,647)
We improved conductance even more with the oversized port design. (Patent #3,216,694)
Patented the easy maintenance port and bonnet style gate valve creating the "Complete Rebuild in 5 Minutes" gate valve. (Patent #3,262,672)
Valve manufacturing operations moved to Pittsburgh, PA.
Vacuum gauge production begins in Newport News, VA.
Introduced wide range manometer with 316L stainless steel diaphragm and a range of 10 -3 Torr to 2 atmospheres
Began selling Rotary Vane Vacuum Pumps.
Eliminated caste SP valve bodies and replaced them with porosity free extruded Aluminum bodies.
Introduced Throttle Valves with ports up to 24 inch (60cm) that are controllable from any PLC with 4 to 20 mA or 0 to 10 VDC .
Introduced electric motor operation of gate valves with ports up to 24 inch (ISO-600).
All VRC products comply with RoHS Directives.
Introduced our low cost stainless steel Diaphragm Manometer with a range of 50 mTorr to 1000 Torr and CE Mark.
Began production of Water Cooled Gate Valves
Introduced the 10-5 Torr to 1500 Torr Super Wide Range Diaphragm Manometer.
An article appearing in Vacuum Technology & Coating acknowledges the superior aluminum welding capabilities of Vacuum Research Corporation.
Began production of Water Jacketed Angle Valves
Vacuum Research continues as a leader in the vacuum component industry. From Aluminum Gate Valves to Rotary Vane Vacuum Pumps, VRC offers a standard of quality and service that continues to evolve with every technology solution.
