An Erie Zone Valve is a type of valve used to control the flow of water in a hydronic heating system. It is typically used to control the flow of water to a specific zone in a building, such as a room or area. The valve is typically installed in the main water line and has a control knob that can be used to adjust the flow of water to the desired zone. The valve is designed to open and close quickly, allowing for precise control of the water flow. It is also designed to be durable and reliable, so it can be used for many years without needing to be replaced. Erie Zone Valves are a great way to control the flow of water in a hydronic heating system, allowing for efficient and precise control of the temperature in each zone.
