This document introduces Bosch Rexroth AG's pneumatic product - Pressure Control Valve to Electrical Proportional Valve, series ED12. The product has a flow rate of Qn= 2600 l/min, with electronic connection through a signal interface and using a multi-pin plug, M12, 5-pin. It is suitable for compressed air media, with a minimum and maximum working temperature of +5°C / +50°C, maximum particle size of 50µm, and maximum oil content of 1 mg/m³. The product is CE certified, with adjustable installation position, an inlet pressure of 12 hysteresis, a working voltage of DC 24 V, a maximum power consumption of 1.4 A, a protection level of IP 65, and a weight of 2.3 kg. The product has a pressure regulation range of 0 / 10 bar or 4 / 20 bar and can be controlled through set value input and actual value output.
This manual describes the E/P pressure regulator valve of the ED12 series, including its analog control method, signal connections (M12 5‑pin), and applicable certifications such as CE and IP65. It outlines the valve's construction features, environmental limits, and required oil‑free compressed air.
Technical data such as rated flow (Qn = 2600 min), working voltage (24 V DC), power consumption (max 14 A), weight (2.3 kg), and housing materials (aluminum and steel) are listed. The document also contains flow‑rate curves, functional diagrams, and pin‑assignment tables for proper installation and troubleshooting. This manual is written in Chinese.
