The butterfly valve is a bidirectional valve. The valve bore and flange surfaces are lined by a rubber liner.
The valves are tested according to EN 12266, ISO5208 – shell test, hydrostatic test.
switching from the “open” position to the “closed” position is carried out by turning the hand lever through
0° to 90°; it is possible to set the hand lever at end positions and interpositons;
manual gear actuation is always recommended for a dimension within the range from DN200 to DN1000.
For small dimensions (DN40 to DN150), the manual gear can be used to make the valve control easier.
-Remote control, extended control
this type of control is suitable in poorly accessible rooms or where a required control level must to be kept;
remote control can be carried out by using a hand lever, manual gear, electric actuator or pneumatic actuator;
Since the choice of an actuator type and equipment depends on operating parameters, it has to be consulted
with the supplier.
