Type S (stainless steel) manifold flow gauge/valve.

Installed at the top of the flow manifold to indicate how fast water is flowing through a zone. The required minimum flow rate for each zone is calculated by Nu-Heat during the design process and indicated on the provided tube layout drawings. A flow gauge/valve is required for each manifold port. For use with current stainless steel Nu-Heat Optiflo manifolds.
