Proportional, electrically pilot operated, intrinsically safe directional control valve, ISAP10… type is used to control the direction of hydraulic fluid flow, and the speed of actuator in the system, which enables direction change of actuator movement – most frequently cylinder piston rod or hydraulic motor, as well as options: start and stop. The value of hydraulic oil flow directed to the actuator is regulated by change of current supplied to the proportional solenoid coils. Valve is adapted for subplate mounting in any working position in hydraulic system. The valve is intended to work in an explosive atmosphere in underground minings (group I) and in machines working on the surface 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.
