Abstract: A valve for dispensing water and air in installations for spraying water under pressure, includes: firstly, a body (2) equipped with two independent circuits (C1, C2), each for circulating a fluid, one air, the other water, each of the circuits including (i) a chamber (5, 15) accommodating a shutter member (6, 16) in the form of a spool, (ii) a duct (7, 17) for admitting the fluid, (iii) a discharge duct (8, 18) for discharging the fluid, and (iv) a drain duct (9, 19) for draining the fluid contained in the discharge duct; and, secondly, control elements for controlling the shutter members so as to make each one move between an open position which allows the fluid to pass and in which the drain duct is shut off, and a closed position in which the fluid is prevented from passing and the drain duct is open.

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.
