Motorised 2 way zone valve with return spring for hydrauylic circuits.

Powered by an electric motor and can assume two operating positions depending on whether the motor is activated or not. Auxiliary swith is activated when the valve switches.
Valves are equipped with an external lever for manually positioning the shut-off ball in its central position.

OPERATION

Without electric power supply the valve is positioned as shown in fig. 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 4 seconds.
