The electromagnetic drive opens against the force of the closing spring 4. The stroke of armature 5 can be limited by the setting screw 8. The hydraulic brake permits slow opening. Fast stroke 9 can be adjusted. If the auxiliary power is interrupted (operating voltage), closing spring 4 closes the valve within 1 second. The closed position of the valve can be monitored by a mountable closed position signal contact.
