Caleffi Manifold Differental By-Pass Valve - 1/2 X 1/2 - 668000.
Caleffi Differental By-Pass Valve 668000work with all the Caleffi Pex Heating manifolds we sell.
The distribution hydronic circuits of the heating fluid in radiant panel systems may be totally or partially shut off by closing the thermo-electric valves with actuators on 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 by-pass kit for Caleffi manifolds maintains the pressure of the supply and return manifold circuits in balance if the flow changes.
