Caleffi 1/2in. x 1/2in. off-center pressure differential by-pass Model 668000
Overview
This is a original Caleffi product and was constructed with quality and concern for the consumer in mind. This item was made to go alond with our other Caleffi products which are available for you to enjoy.
Function
The distribution circuits of the heating fluid in radiant panel systems may be totally or partially shut off by closing the thermoelectric valves inside the manifolds. When the flow decreases, the differential pressure inside the circuit may rise to levels that could cause problems with noise, high rates of fluid speed, mechanical erosion and hydronic imbalance of the system itself. The differential bypass kit for series 663 or 668 manifolds maintains the pressure of the supply and return manifold circuits in balance if the flow changes. The valve can be quickly connected to the series 663 or 668 manifolds, reducing overall size to a minimum.
