Product Description

Self-contained, stainless vacuum regulator for measurement and control. Ideal for process automation in corrosive environments.

Stainless 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
  • Has a bleed valve that adds bleed control from atmospheric air, or 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

Increase Pump Longevity

  • Its utilizes the downstream 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
