Model 450 Vacuum Regulator, Stainless

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 Automatic Process Control 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
