Ridutric three -way pressure proportional valves, antideflagants comparison with ATEX, Iecex, weight, the three -way reduction proportional valves of the three -way pressure*K are piloted devices, assembly on plate, designed to operate in potentially explosive environments. The antideflagrant version complies with the main international certifications: ATEX, IECEX or weight, resulting thus ideal for applications both in surface systems and in underground environments, such as mines. A version designed to operate at low temperatures is also available, up to -40 ° C, maintaining high performance even in extreme climatic conditions. In addition to reducing the pressure from P towards A, these valves allow the return of the flow from A to T when the pressure in the circuit in the valley exceeds the set value. They are available with 12 or 24V power supply, and offer different threaded connection options, both metric and npt. Pressacavi can be purchased separately. The command can take place through a controlled power supply or with the use of an electronic card, to be ordered separately and to be installed in an electrical panel outside the classified area.
