Numatics E22 Series Proportional Regulator

The Numatics E22 Series electronic proportional regulator quickly and accurately adjusts output pressure in relation to an electrical control signal. The regulator operates with pulsed pilot valves that change the pressure in a control chamber. A pressure booster converts the pilot pressure into an outlet pressure with increased flow. The outlet pressure is measured with a pressure sensor and fed into the internal control loop. The regulator is particularly suited for applications with a constant flow, such as flow control over nozzles, turbine speed control, glue and lacquer dosing, or pressure control of welding equipment.
