V1

= impulse solenoid for main cylinder

(next to pneumatics)

V2

= impuse solenoid for auxiliary cylinder

MV1 = solenoid coil for opening

MV2 = solenoid coil for closing

To open energize the solenoids MV1 of V1 and

V2 simultaneously

To close energize the solenoids MV2 of V1 and

V2 simultaneously

To throttle energize the solenoids MV1 of V1

and MV2 of V2 simultaneously
