Unlike SENTRONIC valves, Numatics E Series valves operate with pulsed pilot valves which 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 set-point is established over the electrical plug-in connector as a standard signal [0 to 5 (10) V, 4 to 20 mA].

The E Series is particularly suited for pressure control applications with a constant flow, e.g. flow control over nozzles, turbine speed control, glue and lacquer dosing, or pressure control of welding equipment.

The E22 Series electronic proportional regulators quickly and accurately adjust output pressure in relation to an electrical control signal. They meet requirements of industrial environments including rapid cycling, quick response, and repeatability, which are found in paint, welding, packaging, textile, medical, and many other process applications.

The electrical control signal can be either analog or digital. The analog unit controls any pressure setting directly proportional to the command signal of 4 - 20 mA, 0 - 10 VDC, or 0 - 5 VDC. The optional digital unit uses a 2 bit binary signal to control four user defined pressures eliminating the need for an analog I/O card.
