Series 668S1 TwistFlow pre-assembled distribution manifold for radiant panel systems
with built-in sight flow gauge/balancing valve
Note: This manifold requires 10 Loop Fitting Assemblies (please see below).
Image may not be actual representation of item.
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.
This manifold requires (10) 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" PEX Loop Fitting Assembly
This fitting will connect 3/8" PEX to a loop of the Manifold without requiring the use of a PEX Tool. 680504A: 1/2" PEX Loop Fitting Assembly
This fitting will connect 1/2" PEX to a loop of the Manifold without requiring the use of a PEX Tool. 680555A: 5/8" PEX Loop Fitting Assembly
This fitting will connect 5/8" PEX to a loop of the Manifold without requiring the use of a PEX Tool. 680505A: 3/4" PEX Loop Fitting Assembly
This fitting will connect 3/4" PEX to a loop of the Manifold without requiring the use of a PEX Tool. PEX-AL-PEX Loop Fitting Assemblies Options
682530A: 3/8" PEX-AL-PEX Loop Fitting Assembly
This fitting will connect 3/8" PEX-AL-PEX to a loop of the Manifold without requiring the use of a PEX Tool. 682540A: 1/2" PEX-AL-PEX Loop Fitting Assembly
This fitting will connect 1/2" PEX-AL-PEX to a loop of the Manifold without requiring the use of a PEX Tool. 682545A: 5/8" PEX-AL-PEX Loop Fitting Assembly
This fitting will connect 5/8" PEX-AL-PEX to a loop of the Manifold without requiring the use of a PEX Tool. 682550A: 3/4" PEX-AL-PEX Loop Fitting Assembly
This fitting will connect 3/4" PEX-AL-PEX to a loop of the Manifold without requiring the use of a PEX Tool.
Optional Installation Accessories:
Loop End Cap
If you want to use your manifold to heat multiple zones, you can purchase return side actuators that work along side thermostats. The actuators act as zone valves to allow you to use one manifold to control the temperature in different rooms independently.
