ENGLISH [IND] ELECTRIC BALL VALVE
6. OPERATION OF THE ACTUATOR
The motorised valve consists of an electronic actuator mounted on a conventional valve.
OPERATION. When an electric signal is received, the motor turns to either "OPEN" or "CLOSE" depending on the switching signal until
the internal cam connects to the microswitch, bringing the motor to a stop. When it receives an electric signal again, the motor will turn
in the opposite direction.
- Reversible monophase motor with visual position indicator and exit signal.
- Applications: In 90° turns (or 180° in the case of the three-way ball valve).
- Both AC and DC power supply. Both positions possible with the same actuator. Always follow the connection diagram on the actuator
label.
- Emergency manual operation. The motor will be automatically disconnected by putting the lever in the M (Manual) position.
- Additional auxiliary contacts for transmission position signal.
- WARNING. Do not connect low voltage actuators to higher voltage sources. Similarly do not connect high-voltage actuators
to lower voltage sources. Actuators do not have fuses and incorrect voltages can cause irreparable damage to the device.
J+J Characteristics
- Thermostat controlled temperature: Incorporation of a thermostat-controlled 4W heating system, working temperature between 20°C
and 30°C (68°F to 86°F). In order for the system to work correctly it is important to keep the voltage running through the actuator.
- Safety: The actuator features an automatic electronic cut-off system in case the maximum torque is exceeded. Should this happen, the
device may be manually operated using the handle on the actuator.
- A permanently lit internal LED indicates that the actuator is working correctly. If it starts flashing, this means something is wrong and
the power supply to the actuator will automatically switch off.
Optional accessories:
- Digital positioning System
- Safety block. Independent terminal providing power supply to the actuator in the event of power failure
