Intrinsically safe, proportional, pressure-relief valves type IWZP(P, S, G)E10… are used for controlling pressure in a hydraulic system. Control pressure in the system is a function of the current supplied to the coil of the proportional solenoid. The valves are intended to work in an explosive atmosphere in underground mining pits (group I) and in machines working near flammable substances in the form of gases, vapours, mists (group II). The IWZP(P,S,G)E10… valves have certificates of intrinsic safety: IM1 Ex ia I Ma IM1 Ex ia I Ma IM1 Ex ia I Ma; II 2G Ex ia IIA T3 Gb II 2G Ex ia IIA T3 Gb II 2G Ex ia IIA T3 Gb. They can work with an output intrinsically safe circuit „ia” or „ib” of max. parameters: Ui = 15 V, Ii = 2 A, Ci = 0, Li = 0.
