Proportional pilot operated, intrinsically safe pressure reducing - relief valve IWZCPE10… type is used for maintaining the constant pressure independently of the flow direction. Pressure adjusting is the function of the current supplied to the coil of the proportional solenoid. The valve is intended to work in an explosive atmosphere in underground minings (group I) and in machines working near flammable substances in the form of gases, vapours, mists (group II). The valve has certificates of intrinsic safety: IM1 Ex ia I Ma; II 2G Ex ia IIA T3 Gb. It can work with an output intrinsically safe circuit „ia” or „ib” of max. parameters: Ui = 15 V, Ii = 2 A, Ci = 0, Li = 0.
