Page 5: Safety Instructions And Measures
In case operators intend to use the control 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. - Page 6 Î Check with the plant operator for details on further protective equipment. Revisions and other modifications Revisions, conversions or other modifications of 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 Responsibilities of operating personnel Operating personnel must read and understand these mounting and operating instructions as well as the referenced documents and observe the specified hazard statements, warnings and caution notes. Furthermore, the operating personnel must be familiar with the applicable health, safety and accident prevention regulations and comply with them.

Page 8: Notes On Possible Severe Personal Injury
Safety instructions and measures 1.1 Notes on possible severe personal injury DANGER Risk of bursting in pressure equipment. Valves and pipelines are pressure equipment. Improper opening can lead to valve components bursting. Î Before starting any work on the 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 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 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.
