Product Description

MAIN CHARACTERISTICS : These are powered by an electric motor and can assume two operating positions depending on whether the motor is activated or not. One or two auxiliary switches can be installed on request. These are activated when the valve switches. Valves are equipped with an external lever for manually positioning the shut-off ball in its central positing.

OPERATION : Without electric power supply the valve is positioned as shown in flig.1: He valve is closed. When it is powered, the servomotor overcomes the spring force and moves the ball from path A to an intermediate position in about 10 seconds and keeps it in that position until the electric power supply is cut out (fig.2). When the electric power supply is cut out, the return springs bring the shut-off ball back to path A in about a seconds

USING THE MANUAL LEVER : A lever is located on the side of the motor. This is used to position the shut-off ball in an intermediate positing (fig.3). This is helpful when filling or emptying the heating system. The lever reset, form manual to automatic, takes place automatically whenever the valve is electrically activated.
