The accessible feed check valve is used in high-pressure systems such as boilers, heat exchangers, and other hydraulic operations where low-pressure valves are used for low-risk operations. 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.
Prevent the backflow of water from the boiler to the pump when the boiler pressure is more than the pump pressure or when the feed pump stops working. For additional information regarding the product, please contact the dubby support team.
