OPTION ELECTRICAL BALL VALVE DRIVE

The electrical ball valve drives for control of two operating modes are available in three control voltages 230 V, 115
V or 24 V DC.

16.4 OPTION SOLENOID VALVE UNITS FOR BLOW BACK, TEST GAS FEEDING AND CONTROL
OF THE PNEUMATIC DRIVES
All solenoid valve units contain a 3/2-way solenoid valve for control of the pneumatic drive. One way of the solenoid
valve is used for switching the ball valve the other for ventilation and hence resetting the ball valve. Furthermore
depending on demand 2/2-way solenoid valves for blow back and/or test gas feeding are existing.

Feed the back purge gas with a nominal width as big as possible in order to avoid
losses of pressure in the feeding line during the back purge action.
