  • 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 Safety instructions and measures Referenced standards and regulations The control valves comply with the requirements of the European Pressure Equipment Direc- tive 2014/68/EU. Valves with a CE marking have a declaration of conformity, which in- cludes information about the applied conformity assessment procedure. This declaration of conformity is included in the Appendix of these instructions (see section 10.2).

  • Page 8: Notes On Possible Severe Personal Injury

    Î Wear personal protective equipment. Risk of injury due to incorrect handling of oxygen or cryogenic gases. The Type 3248 Valve is frequently used for oxygen service or applications with cryo- genic gases. Oxygen is a hazardous substance, which reacts quickly, leading to com- bustion or explosions.

  • Page 9: Notes On Possible Personal Injury

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

  • Page 10: Notes On Possible Property Damage

    Risk of valve damage due to the use of unsuitable tools. Certain tools are required to work on the valve. Î Only use tools approved by SAMSON (u AB 0100). Risk of valve damage due to the use of unsuitable lubricants. The lubricants to be used depend on the valve material. Unsuitable lubricants may corrode and damage the valve surface.
