config�uration and Funtion
The pilot valves of Type 6524 and 6525 consist of a tilting
solenoid pilot control valve and a pneumatic seat valve.
The operating principle enables high pressures to be control-
led with low power consumption and short switching times. All
valves come with emergency manual control as standard.
Type 6524 is also available as a 2 x /2-way valve. It consists
of two tilting solenoid pilot control valves and a pneumatic seat
valve.
