MAIN CHARACTERISTICS

SF 415 valves are 4-way valves for hydraulic circuits.
They are outstanding for compactness and can be used in heating systems or as control components in heat exchange coils in the terminal units of air conditioning systems.
They are charged by an electric motor and can assume two operating positions depending on whether the motor is activated (Fig. 2) or not (Fig.1). An auxiliary switch can be installed on request and activated when the valve is switched. The valves are furnished with an external lever for manual positioning of the shutoff ball in a central position (Fig. 4). They also have a built-in by-pass to balance the hydraulic circuit when the valve is closed.
The load loss generated by the by-pass can be regulated using a graduated knob placed on the side of the valve.
