    Safety instructions and measures 1.1 Notes on possible severe personal injury DANGER Risk of bursting in pressure equipment. Control valves and pipelines are pressure equipment. Improper opening can lead to valve components bursting. Î Before starting any work on the control valve, depressurize all plant sections concerned as well as the valve.

  • Page 9: Notes On Possible Property Damage

    Risk of personal injury due to preloaded springs. Valves in combination with pneumatic actuators with preloaded springs are under tension. These control valves with SAMSON pneumatic actuators can be identified by the long bolts protruding from the bottom of the actuator.
  • Page 10 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 cor- rode and damage the valve surface.
