Stainless Vacuum Regulator | Model 450 | Vacuum Controller (Torr)

Description

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

Super simple to use: just dial in your vacuum set point
Maximizes pump down speed and uses throttle vacuum control to increase pump longevity
Ideal for altitude simulation, distillations, composites research and industrial vacuum processes
Stainless steel valve and vacuum path for corrosive or hostile applications

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

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

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

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

Accuracy | +/- 2 Torr 1-760 Torr

The Model 450 was previously available in a Brass Wetted Materials Option, but that has been discontinued.

DigiVac also offers another all Stainless Vacuum Regulator. The Vapor Pressure Controller | VPC
