Proportional valves regulating scope of compensated antideflagrant ATEX, IECEX, weight, the QDE3K valves* are proportional range valves of flow rate with electric baric compensation, for plate assembly. 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). These valves work on 2 or 3 -way depending on how the assembly interface is made. They are used for adjusting the flow rate in hydraulic circuit branches or to regulate the speed of hydraulic actuators. control of the speed of hydraulic actuators. The valves are available for 12 or 24V power supply. Different types of connection, metric or NPT are available. Pressacavi can be purchased separately.
