The product is used to control the supply of water to the boiler and to prevent the escaping of water from the boiler when the pump pressure is less, or the pump is stopped.
Feed check valves are one of the most important components of the boiler which control the flow of water from the feed pump to the boiler and further prevent the backflow of water from the boiler to the pump when the boiler pressure is more than the pump pressure or when feed pump stops working. For additional information regarding the product, please contact the dubby support team.
