Antideflagant proportional valve reducing pressure ruling ATEX, Iecex, weight Le ZDE3K* are proportional proportional valve of direct pressure, for plate assembly. In antideflagrant version. These solenoid valves comply with the ATEX, IECEX and weight requirements and are suitable for use in potentially explosive atmospheres, for surface or mine systems. A version for low temperatures is also available (up to - 40 ° C). They are used to reduce the pressure in secondary branches of the circuit, ensuring the stability of the pressure regulated also as the flow of the flow that crosses the valve.
