Counterbalance valves setting corresponds to the opening pressure of pressure relief section. pressure determines the max load which counterbalance valve is able to hold. Usually the setting pressure value must be at least 1.3 times the max load induced pressure to hold. tolerance allows induced loads safe holding.
With a pressure vacuum breaker, however, a drop in the pressure of the water enables the spring to snap the check valve shut. As soon as the water pressure drops, the check valve closes and backflow does not occur.n a pressure vacuum breaker, the water travels through a check valve and causes a poppet to raise up a guide into an air inlet. The air inlet also has a valve which ordinarily remains closed.
