Regulatory valves of proportional antideflagrant pressure pressure compliant ATEX, IECEX, weight Le pde3k*, pre3k*, pre10k, pre25k*and pre32k*are antideflagants regulatory pressure on proportional, direct and piloted pressure, 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). They are used to modulate the pressure of the hydraulic circuit and allow you to use the entire pump flow also to pressure values ​​close to the calibration value. These valves have a mechanical pressure limitation function in order to offer greater safety safety. The valves are available for 12 or 24V power supply. Different types of connection, metric or NPT are available. Pressacavi can be purchased separately.
