2.4  Technical data

Actuators 

Standard actuators:

•  Manual
•  Pneumatic 

Manual valves are closed by turning the hand wheel 

clockwise. 

Pneumatic actuators are with a fixed stroke and do not 

require external controls. The pneumatic actuator is designed 

for a nominal supply of 6 bar (90psi). Use correct sized 

pneumatic hoses to ensure sufficient air flow.
The air must be clean, dry, lubricated and properly filtered.  

An air quality of minimum requirement to ISO 8573-1:2010 

[7:4:4] is recommended. If any component used on the valve 

has a stricter requirement, the stringent shall prevail.

Pneumatic actuator noise level may exceed 85 dB and it is 

recommended to use ear protectors when working near the 

valve.

Consult the manufacturer’s instructions on actuator 

requirements or/and limitations. If actuator is changed or 

valve needs adjustment, follow the Maintenance instructions.
