SINTESI 6-WAY BALL VALVES OPERATION The 6-way valve consists of two three-way ball valves which are moved simultaneously by the same control rod. Therefore, a single 6-way motorized valve replaces four 2-way motorized valves, simplifying the control and installation. With the 6-way valves you can therefore change the state (hot/cold) and the complete hydraulic insulation of the terminal unit from the distribution, when required. HEATING OPENING COOLING OPENING OVERPRESSURE DISCHARGE SYSTEM When the valve is in the closed position (position 45°) the hydraulic circuit between the terminal unit...

SINTESI 6-WAY BALL VALVES MATERIAL USED EPDM - PEROX SIDE SEAL ANTI-FRICTION RING EPDM - PEROX PHOSPHOR BRONZE EPDM - PEROX KVS DISCS The 6-way valve is supplied in the configuration which guarantees the maximum value of Kvs, i.e. of flow rate, for each of the two sections. The flow rates for each of the two sections are actually different: the heating flow rates are normally lower than the flow rates required for cooling, due to the lower ΔT. For this reason, each valve is supplied with a kit consisting of 4 pairs of perfectly interchangeable discs through which it is possible to manage the...
