Abstract
A water and/or air dispenser for snowmaking system includes water and/or air supplying ducts and is equipped with at least one valve (9) associated with an electric actuator (10), the actuator (10) being connected to an electric power source (12, 19) and associated with its own management unit (11) to ensure the operation of the valve (9) between the open and closed configurations thereof. The dispenser is associated with security elements able to cause the valve (9) to be positioned in a known security configuration, for example tightly closed, in case of voltage cut-off at the electric source (12, 19), the security elements being integrated and including a capacitor-type electric unit (16), connected to the electric power source and to the actuator (10), the capacitor unit being able to store, and then return, a quantity of energy necessary for complete actuation of the valve, to implement the security elements.
