Refill Valve
The AQUAVENT valve helps prevent pressure shocks while draining and refilling water supply pipes. It prevents shock conditions by allowing the system to vent properly without wasting water, whether the drain-down is intentional or unintentional due to low water or power interruption.
The AQUAVENT also decelerates the water column by releasing air during filling, closing once all air is removed. It features a balanced design that seals the system with minimal water loss. During draining, the valve eliminates negative pressure with a vacuum break in the draining riser.
