Water loss and cross contamination reduction valve FlowGuard II™, for all wet barrel hydrants
The AVK FlowGuard II™, bi-directional check valve, is designed with safety in mind. In the event of a traffic accident, the ball will rise to seal off the flow from the main line. A small stream of water is allowed to flow, reducing possible water hammer and indicating the hydrant has been damaged.
