3. BALL VALVE
The working pressure of the valve reduces with increasing liquid temperature, as shown in the accompanying chart.
Air supply: Filtered air PNEUROP/ISO class 4.
Air pressure: 6 bar ± 15%. In case of lower presure, ask to the technical department to check the torque of the actuator.
Temperature range for the actuators:
Rotork aluminium actuator: -50ºC to 70 ºC.
Prisma Plastic actuator: -32ºC to 90ºC.
All the actuators include NAMUR VDI/VDE 3845 interface for the electrovalve and the limit switch box.
Rotork actuators can be ajusted 0-90º ± 5º, except DN15 and DN20 double acting.
Prisma actuators are ATEX certified (ATEX EXII2Gc IP67 T6).
To get more technical information about the actuators, please refer to the instruction manuals attached to the valve documentation.
