Der polarisierte Elektromagnet ist eine gültige Lösung für alle Anwendungen, bei denen Energieabsorption oder elektromagnetische Erwärmung, auch wenn sie nur sehr begrenzt sind, nicht toleriert werden. Der bistabile Befehl hat den Vorteil, dass er nur in der Schaltphase Energie benötigt: Dies ist dank des Vorhandenseins eines Permanentmagneten in der Spule möglich, der eine kombinierte Aktion mit dem durch die elektrische Wicklung induzierten Magnetfeld ausführt. Die Dauer des Impulses, der zur Erzeugung der Zustandsänderung erforderlich ist, beträgt einige Hundertstelsekunden, während die Polarität der Stromversorgung das Öffnen oder Schließen des Ventils bestimmt. Die sehr begrenzte Energieaufnahme dieser Produkte macht sie besonders geeignet, wenn Batteriestrom verwendet wird. Die Erwärmung des Elektromagneten ist aufgrund der geringen Energieaufnahme nahezu 

the polarized electromagnet is a valid solution for all those applications where energy absorption or electromagnet heating, even very limited, are not tolerated. The bistable command has the advantage of requiring energy only in the switching phase: this is possible thanks to the presence of a permanent magnet inserted inside the coil, which performs a combined action with the magnetic field induced by the electric winding. The duration of the impulse necessary to generate the change of state is a few hundredths of a second, while the polarity of the power supply determines the opening or closing of the valve. The very limited energy absorption of these products makes them particularly suitable when using battery power. The heating of the electromagnet is almost zero as a consequence of the low energy absorbed.

bistable latch voltages: 9v 12v 24v

NB INSTALLAZIONE ELETTROVALVOLA BISTABILE PER GAS METANO IN LUOGHI ARIEGGIATI, ALL'APERTO, NON IN LUOGHI CHIUSI, NON IN POZZETTI, NON DENTRO o SULLE IMBARCAZIONI-CAMPER ECC. NON SOTTO ALLE INTEMPERIE.

NB INSTALLATION OF BISTABLE SOLENOID VALVE FOR METHANE IN PLACES ARIEGGIATE, OUTDOORS, NOT IN CLOSED PLACES, NOT IN WELLS, NOT INSIDE OR ON BOATS-CAMPERS ETC. NOT UNDER WEATHER.

question:

I would like to kindly know, if such type of solenoid valve

requires a positive impulse to open

and a negative impulse to return to the closed position

or is a second always positive impulse enough?

reply:

I confirm that the two pulses must be of inverted polarity to open and close the solenoid valve, for further details you can refer to the attached wiring diagram (see product images)

Is it possible to use it for LPG gas?

the version with NBR membrane for natural gas

the version with VITON membrane for LPG

can the solenoid valve be kept indoors?

NO, they must be outdoors

can the solenoid valve stay in the rain?

YES, if you buy the IP67 protected version

can I assemble it that I am not an editor with the requirements?

NO
