A2660401 Truflow JR 4 Zone Manifold by Uponor (Wirsbo)
The TruFLOW™ Jr. Manifold system
4-loop manifold with Isolation and Balancing Valves comes fully assembled and ready for installation.
This manifold with isolation valves allows connection to either the Uponor Thermal Actuator or Motorized Valve Actuator.
For supply and return connections, the manifolds use R32 unions to accommodate any of Uponor's manifold adapters, allowing quick and easy connections to Wirsbo hePEX™ plus and Uponor multi-layer composite (MLC) tubing (formerly MultiCor®) as well as copper piping.
The loop connection features an R20 thread to accommodate 5⁄16" to 3⁄4" PEX or 1⁄2" and 5⁄8" MLC tubing. For PEX tubing, use a QS-style or ProPEX® fittings. For MLC tubing, use only Uponor MLC press fittings.
The manifolds feature o-ring sealed connections to ensure a leak-resistant and secure connection. Additionally, the manifolds include calibrated balancing valves to accurately balance flow and temperature in all radiant loops. The internal diameter (i.d.) of the manifold body is 1 3⁄16" and easily allows up to 14 gallons per minute (gpm). The loop outlets have a flow coefficient (Cv) of 1.9 gpm.
