Caleffi TwistFlow Advantages
1. Out of the box on to the Wall — Manifolds are factory pre-assembled and
pressure tested.
2. Universal compression fittings —
680 series fittings are compatible with all
PEX pipe brands meeting ASTM F876 dimensional standards; 682 series fittings
are compatible with all PEX-AL-PEX pipe brands meeting ASTM F1281
dimensional standards.
3. Built-in sight-flow meters integrated with adjustable balancing valves:
1. Simplifies circuit calibration without cumbersome reference graphs.
2. Allows accurate
1
/4 to 2 gpm flow rate adjustment to each circuit by simply reading
the flow rate on the integral graduated scale.
3. Determine actual btu output per zone with the optional snap-on thermometer.
4. One-piece casting design — Superior leak resistance
5. Distinctive curved manifold shape results in:
1. PEX nesting for flush in-wall mounting.
2. Constant cross-sectional area for negligible pressure loss and high flow
with less noise and smaller pump requirement compared to straight
extruded designs.
6. Pre-assembled with Automatic Air Vents — Air vents have hygroscopic caps
that close when water is near the vent preventing water from spitting.
7. Complete line of accessories — Flexible field installation to meet any
radiant system need.

Feature Comparison
Features
Factory pressure-tested single piece —————Exclusive high-quality construction wih less potential leak points
cast brass supply and return manifolds compared to extruded designs
Built-in Sight Flow Meters integrated —————Allows easy and accurate 1/4 - 2 gpm flow rate adjustment to
with adjustable circuit balancing valves each circuit by simply reading the flow rate on the integral
graduated scale. Simplifies and speeds up circuit calibration
without cumbersome reference graphs.
Manifold casting indents and offset —————Narrow profile permits in-line ‘tubing-to-fitting’ runs and allows
brackets nesting of PEX for flush mounting inside 2x4 or 2x6 wall cavities.
Universal self-adjusting diameter PEX NO NO NO NO NO Self-adjusting diameters accomodate slight PEX variances from
and anti-galvanic PEX-AL-PEX fittings different manufacturers, are corrosion resistant, and have no
for all pipe brands connection leaks with any ASTM dimensional compliant tubing.
Broad PEX and PEX-AL-PEX piping size ———Provide more PEX sizing flexibility and compatibility with all PEX
compatibility: 5/16" - 3/4" pipe brands meeting ASTM dimensional standards.
Shutoff Ball Valves with Gage Port Optional ——For temperature gage. Knowing flow rate and temperature,
BTU can be calculated.
Manual open/automatic return for NO NO NO NO NO Purge and fill each circuit without taking off the actuators by
individual circuits with optional Caleffi manually opening the return manifold shut-off valve. System
TwisTop™ actuators commissioning and electrical check is simple and quick. Refer to
Caleffi Sell Sheet SS-101.
Optional Differential By-Pass ———Maintains constant flow through each circuit as actuators cycle.
Simplifies by-pass piping when required.
Pre-assembled standard manifolds Automatic Automatic — Automatic — Easy specification, ordering, and installation with peace-of-mind
complete with automatic air vent and air vent air vent air vent quality for ultimate customer satisfaction. Speeds installation time
fill/drain valve on supply and return optional optional optional and assures a quality system.Automatic air vent closes
manifolds, adjustable brackets automatically when water is near the vent.
