Operation

Once correctly installed, the operation of the IPVA10EK valve is dependent only upon the switching of the electrical
supply to the valve:



Normally-open valves close when the electrical supply to the valve is switched on; the valve opens
automatically when the electrical supply is switched off.



Normally-closed valves open when the electrical supply to the valve is switched on; the valve closes
automatically when the electrical supply is switched off.

WARNING

Do not touch the surface of the valve coil during operation. It may be hot.
