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 (20) Loop Fitting Assemblies:
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.
