L. J. Engineering, Inc. sets the standard for precision vacuum regulators, vacuum flow control devices and digital vacuum gauges. Our products serve industrial and military markets. Numerous U.S. Patents have been granted for our products, which include: vacuum regulators and pneumatic flow control devices, automatic activation devices for parachutes as well as supporting digital altitude chamber test equipment to evaluate automatic activation devices and wrist altimeters.
Our products are specified and trusted around the world for the most demanding applications. Model 494 Vacuum Regulator with flow sensor controls vacuum or pressure using a proportional valve servo control loop. Regulator setpoint can be adjusted via analog control signal, onboard or external potentiometer. The electronic vacuum regulator accepts an analog control voltage signal, which precisely operates valves as required to maintain the desired set vacuum pressure.
