Pressure Control: E22 Proportional E22 Series Unlike SENTRONIC valves, E-Series valves operate with pulsed pilot valves which change the pressure in a control chamber.

2 Pressure Control: E22 Proportional E22 Series Unlike SENTRONIC valves, 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 setpoint is established over the electrical plug-in connector as a standard signal [ to 5 () V, 4 to 2 ma]. 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. Electrical connector Display Pilot valves Rolling diaphragm Exhaust poppet Pilot filter Supply poppet

3 Proportional Pressure Control: E22 Operating Principle Increasing pressure The inlet poppet is operated and air flows from port to port 2. Maintaining pressure The poppets are in their central position: the flow between port 2 and port or port 3 is blocked. Exhausting pressure The exhaust poppet is lifted and air flows from port 2 to port 3. Specifications Fluids: Air, neutral gases Pressure range: to 5 psi (.2 bar) Ports: (directly operated) /4, 3/8, /2, (NPT, GTap or BSPT) Construction: Poppet valve Actuation: 2 control valves Setpoint: V, 4 2 ma, 5 V Options: Internal pressure switch Analog output (feedback) 2

4 Pressure Control: E22 Proportional Introducing the E22 Series 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 4-2mA, -VDC, or -5VDC. 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.
