Intended use
The Type 3963 Solenoid Valve is mounted onto pneumatic linear or rotary actuators
(depending on the version) to control them. Upon failure of the air supply, the solenoid valve
vents the actuator, causing the valve to move to the fail-safe position determined by the
actuator. The device is designed to operate under exactly defined conditions (e.g. operating
pressure, temperature). Therefore, operators must ensure that the solenoid valve is only used
in applications where the operating conditions correspond to the technical data. In case
operators intend to use the solenoid valve in other applications or conditions than specified,
contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
Î
Refer to the technical data and nameplate for limits and fields of application as well as
possible uses.
Reasonably foreseeable misuse
The solenoid valve is not suitable for the following applications:
− Use outside the limits defined during sizing and by the technical data
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing maintenance activities not specified
Qualifications of operating personnel
The solenoid valve must be mounted, started up, serviced and repaired by fully trained and
qualified personnel only; the accepted industry codes and practices are to be observed. Ac -
cording to these mounting and operating instructions, trained personnel refers to individuals
who are able to judge the work they are assigned to and recognize possible hazards due to
their specialized training, their knowledge and experience as well as their knowledge of the
applicable standards.
Explosion-protected versions of this device are to be operated only by personnel who has un-
dergone special training or instructions or who is authorized to work on explosion-protected
