Caleffi 1-1/4" TwistFlow Inverted Manifold w/ Temp Gauge (8 Outlets)

Note: Image may not be actual representation of item. Series 668S1 TwistFlow pre-assembled distribution manifold for radiant panel systems with built-in sight flow gauge/balancing valve 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. 1-1/4" NPT inlet ball valves Maximum working pressure: 150 psi (10.3 bar) Maximum temperature: 180°F (82°C) Maximum peak temperature: 200°F (93°C) Loop Cv: 1.23 (combined supply & return ports) Outlet center distance: 2 inches This manifold requires (16) Loop Fitting Assemblies: PEX Loop Fitting Assemblies Options 680507: 5/16" PEX Loop Fitting Assembly This fitting will connect 5/16" PEX to a loop of the Manifold without requiring the use of a PEX Tool. 680503A: 3/8" P...
