Note: This manifold requires 12 Loop Fitting Assemblies (please see below).
Mr. PEX 1-1/4" Stainless Steel manifolds achieves the highest level of long term corrosion resistance by
using a bright annealed high-grade, Type 304, stainless steel with high nickel content. This creates a stable
material structure with low levels of ferrite and magnetism. To eliminate the possibility of contact corrosion,
all fittings connected to the manifold are nickel-plated. The manifolds are fully assembled, ready for mounting,
The supply side features adjustable flow-meters for flows up to 1.45 gpm per loop, and the return side has
balancing on/off valves, in accordance with DIN EN 1264-4. The adjustable flow-meter allows for a positive
shut-off and the manual plastic cap on the return valve can be removed to accommodate a valve actuator. The return balancing valve disc is designed to enable exact adjustments of small flows while still
being able to handle large flow with minimal resistance. The branch Cv value is 1.38 and the manifold body
accommodates flows up to 14 gpm.
The supply and return manifold bodies both have wells to accomodate optional thermometers, and a multi-function swivel End Cap allowing for Fill/Drain or Vent. Each inlet of the manifold has a G 1" thread (BSP straight metric thread) allowing for easy connections of the supply and return
mains. Use only MrPEX® Manifold Option adapters for appropriate connection. The branches have Eurokonus
(EK20) connections, and all MrPEX® EK20 compression fitting assemblies (PEX to EK20 or PEX-AL-PEX to EK20)
can be used to connect tubing to the manifold.

Actuators
- 5120700: Thermal Actuator for Mr. PEX Manifolds (4 Wire)
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.
