AccessoriesSkyStarBalancing valves independent from the system pressureThe balancing valve and a combined 2 way valve allow the regulation of the water flow value autonomously, regardless of the system pressure, and the control of the flow by using an ON/OFF electro-thermal actuator.The balancing valve allows you to balance the hydraulic system by supplying the required water flow, for each fan- coil, and to maintain it even under partial load conditions. • A graduated ring nut placed under the valve allows you to set the flow rate value and also allows direct reading of the set value.Valve operation logic“p1” is the valve inlet pressure. • “p3” is the outlet pressure. • “p2” is the diaphragm activation pressure, which allows differential pressure “p2” – “p3” to be maintained at a constant value, in order to guarantee the water to flow at the set value.
