The EV04 series electric proportional valve is an electric proportional valve product launched by Bosch Rexroth. It has a DC24V input voltage, a maximum working pressure of 8 bar, and a rated flow rate of 350 l/min.
This manual describes the Bosch Rexroth EV04 series electric proportional E/P pressure regulate valve, a pneumatic valve that uses analog control signals (4‑20 mA or 0‑10 V) to regulate compressed‑air pressure. It lists the valve’s construction features, environmental limits, and required oil‑free air quality.
Technical data such as maximum flow (350 l/min), supply voltage (24 V DC), protection class (IP54), and wiring connections with multi‑core plugs are presented together with electrical diagrams and pin‑assignments for various signal options. Installation notes cover inlet pressure ranges, required fusing, and EMV shielding requirements. This manual is written in Chinese.
