Z50A1ESD is the new generation of our monoblock directional control valves - solenoid operated Z50ES and also offers perfect choice whether you are designing a new system or just simply trying to get more out of your current system. With two special spools and option of having 7 spool valve body configuration these valves can meet the specific needs of your application. Its new feature is that the control is achieved by double solenoid with spring return to neutral position, available with emergency manual override. Due to it's relation to the earlier Z50ES the bodies are interchangeable requiring only spool seals change.
