Pre-assembled distribution manifolds

for radiant panel systems

series 663 & 668S1

Function

Distribution manifolds for radiant panel systems are used to

optimally distribute the heating fluid in floor heating system circuits

and ultimately improve the control of heat emission from the panels.

The manifolds ensure that the flow to each circuit is regulated

precisely and also control the shut-off, venting and automatic

removal of air from the system.

The balancing is accomplished by turning a hex wrench into the balancing valve in each supply outlet. The chart on page 7 shows the number of turns for reaching the desired value of flow and Δp.

37288_CNA6:37288_CNA6 8/6/08 8:40 AM Page 4 Hydronic characteristics for TwistFlow- 668S1 To determine the hydronic characteristics of the circuit, we must calculate the total pressure loss experienced by the flow of fluid as it passes through the manifold components and the radiant panel circuits. From a hydronic standpoint, the manifold unit and circuits can be shown as an assembly of hydronic elements that are arranged in series and parallel to each other. ΔPBall v. ΔPF Man.
