BUTTERFLY VALVE

3.1 VERICATION OF VALVE TYPE
On opening the packaging please check that the valve is the model ordered.
Check that the actuator model corresponds with the code number ordered. Make
especially sure that the voltage indicated on the actuator label corresponds to that of
your mains supply (actuators do no incorporate valves, meaning that incorrect voltage
will cause irreparable damage to the device).
All valves are electrically and hydraulically tested in the factory. Valves will always be
replaced in the event of any justifiable claim.
For more technical information about the actuators, please refer to the instruction
manuals attached to the valve documentation.
3.2 GUARANTEE
This equipment has been extensively tested in the factory, thus guaranteeing it is in
perfect working condition. This guarantee will be applicable assuming the device has
been properly installed and not used in an incorrectly. For this reason, this equipment
must be installed by a suitably qualified person.

Valve operating torque
Operating torque values at rated pressure (PN) and 20 °C as supplied by default from the factory. Installation and operating condi-
tions (pressure and temperature) may affect these values.
The actuator required for an automatic operation must be calculated according to some safety factors that were determined in tests
carried out in the factory.
