In many hydronic systems, theres a need to divide the overall system flow into equal streams that pass through several identical components. The physics necessary for this are simple: If the flow resistance of each piping path from a common source point to a common return point is the same, the flow will divide equally. … See more Figure 1 shows a simple representation of reverse return piping through two identical components, each in its own branch piping. It also shows a direct return piping layout for … See more However, just because two or more branches are piped in reverse return does not imply that each branch will operate at the same flow rate. … See more Notice that the supply pipe size decreases as the circuit moves away from the heat source while the return pipe size increases. Pipe size changes are made to keep flow velocity or … See more Reverse return piping subassemblies make sense when two or more identical devices require equal flow proportions and have a common supply. An example would be multiple … See more WebMar 1, 2009 · Control valves should normally be on the return side of hot or cold systems. Reason for hot systems: 1) also throttling and keeping gases in solution, 2) reduce heat transfer to the actuator. Some actuator mfrs. indicate ~140-160°F temperature limits and require they be installed on returns.
