DESCRIPTION APPLICATION
Direct operated proportional spool valve with 4 connections in These valves are suitable for applications in explosion-hazard areas,
5-chamber system. Precise spool fit, low leakage, long service life open cast and also in mines. The stainless execution is especially
time. Proportional to the solenoid current, the spool stroke, the spool suitable for the use in wet and salty environment. Proportional spool
opening and the valve volume flow increase. The pressure tight en- valves are perfectly suitable for demanding tasks due to the high re-
capsulated Ex-protection solenoid coil prevents an explosion on the solution, large volume flow and low hysteresis. The applications are
inside penetrating to the outside as well as an ignitable surface tem- in the industrial as well as in the mobile hydraulics for the smooth

perature. control of hydraulic actuations.
