Description

Self-contained, throttle vacuum regulator for maintaining pressures between 2 and 760 Torr helps increase vacuum pump longevity.

  • Super simple to use: just dial in your vacuum set point
  • Utilizes downstream vacuum control which increases pump longevity
  • Ideal for altitude simulation, distillations, composites research and industrial vacuum processes

Throttle Vacuum Regulator | Simple in Form and Function

  • Works in conjunction with a precision isolated transducer and a proportional solenoid valve to measure and control vacuum
  • In addition to throttle, it also has a bleed valve that adds bleed control from atmospheric air, or the customer supplied gas

Maximizes Pump-Down Speed

  • Designed with a much larger bore (9/32″) proportional valve (compared to alternatives) that allows the controller to make precise changes in vacuum flow to achieve a very stable vacuum level
  • Microprocessor runs an intelligent algorithm drives a proportional valve using a PWM technique, which allows precise positioning of valve without developing excessive heat or generating EMI (electromagnetic interference)
  • Constantly monitors system pressure and readjusts valve orifice to maintain desired target pressure, even in vessels with dynamic gas loads or changing set-points

Don’t Worry | Automate

  • Reads current system vacuum via an isolated transducer, and compares that reading to the desired vacuum set-point
  • Ideal for altitude simulation, distillations, composites research and industrial vacuum processes where repeatability can be translated into better experiments or product yield
  • For corrosive environments you should choose the Model 450 Stainless 

Increase Pump Longevity

  • Its utilizes the throttle vacuum control method (throttling the pump) which increases pump longevity by keeping the pump operating closer to its base vacuum pressure
  • It is super simple to use: simply dial in the pressure to be maintained and it takes care of the rest
  • Every Model 450 Brass | Throttle Vacuum Regulator comes pretested and calibrated under actual vacuum against a NIST standard
  • NIST certification and documentation is available for an additional fee
