Mike, To change from the Erie actuators to our brand you would have had to change the body of the valve too. The bodies are directional. They need to be installed in the with flow in the direction from A to B on the valve. When they are installed in an incorrect flow direction they will work as far as controlling the zone oporation but when they close they are closing wiht the flow not against it. This allows the flow path to slam the valve closed and causes hammering. I would recommend confriming the valve body installation in relation to the direction of flow. You can call into tech support anytime to discuss 414-238-2360.
