Electronic Pressure Regulators
Product Details
Equilibar is proud to represent electronic pressure regulators by Proportion-Air, an innovative leader in precision elecronic pressure control.
100% designed and manufactured in the USA, Proportion-Air is able to quickly customize pressure controllers for virtually any application. For customers requiring custom or turn-key solutions, learn about our automated pressure control systems.
Proportion-Air pioneered the use of proportional valve modulation to minimize pressure oscillations in precision applications. The MPV/QPV regulators are ideal for controlling Equilibar's precision back pressure and vacuum regulators.
When purchased through Equilibar for this purpose, these MPV/QVP regulators are specially tuned for high performance right out of the box, saving you time on system set-up and tuning.
