  • Page 5: Safety Instructions And Measures

    SAMSON must be contacted. SAMSON does not assume any liability for damage resulting from the failure to use the valve for its intended purpose or for damage caused by external forces or any other external factors.
  • Page 6 Î Check with the plant operator for details on further protective equipment. Revisions and other modifications Revisions, conversions or other modifications to the product are not authorized by SAMSON. They are performed at the user's own risk and may lead to safety hazards, for example. Fur- thermore, the product may no longer meet the requirements for its intended use.

  • Page 7: Notes On Possible Severe Personal Injury

    Safety instructions and measures Referenced standards and regulations The control valves comply with the requirements of the European Pressure Equipment Direc- tive 97/23/EC. Valves with a CE marking have a declaration of conformity which includes information about the applied conformity assessment procedure. This declaration of confor- mity is included in the Appendix of these instructions (see section 10.2).

  • Page 8: Notes On Possible Personal Injury

    Risk of personal injury due to preloaded springs. Valves in combination with pneumatic actuators with preloaded springs are un- der tension. These control valves with SAMSON pneumatic actuators can be identified by the long bolts protruding from the bottom of the actuator.
