1-1/4" Wirsbo (brass) Manifolds, 3-loop, with valves

The Wirsbo 1 +á Valved Manifold (dezincification resistant brass) is used in combination with a Valveless Manifold. The Valved Manifold features internal flow-balancing valves and can seat both the Thermal and Motorized Valve Actuators for multi-zone installations. Manifold has a R32 union connection on one end and a R32 Male connection on the other. Manifold system is modular in that the 2-, 3- or 4-loop manifolds can be ganged together to create the required size manifold for any installation. Manifold Gasket (A2403232) and Balancing Caps (A2600004) for each loop are included with the manifold. The Valved Manifold is used as the return manifold.
Maximum recommended flow to the manifold based on manifold body diameter is 14.0 gpm.
