4.1 Function
On switching on of the solenoid drive (800) the solenoid core (207) is pulled against the upper part of
housing (106). The pressure spring (503) is further prestressed and the valve disk (200) opens the
valve cross section. The valve is open.
On shutting off, supply interruption or supply failure the valve closes to the solenoid drive. The valve
disk (200) closes due to the pre-stress of the pressure spring (503). The valve is closed.
4.2 Technical data
Opening times: 0,3 – 0,7s , depends upon nominal width
Closing times:  1s
