Throttle vacuum regulator to increase pump longevity

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

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

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
For corrosive environments you should choose the Model 450 Stainless

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
