Intended use
The Type 3969 Solenoid Valve is mounted onto pneumatic linear or rotary actuators to con -
trol 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 operat-
ing 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 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 and serviced by fully trained and qualified
personnel only; the accepted industry codes and practices are to be observed. According 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 spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.
Explosion-protected versions of this device must be operated only by personnel who has un-
dergone special training or instructions or who is authorized to work on explosion-protected
devices in hazardous areas.
