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.
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).
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.
Safety instructions and measures WARNING! Risk of burn injuries due to hot or cold components and pipelines. Depending on the process medium, valve components, and pipelines may get very hot or cold and cause burn injuries. Î Allow components and pipelines to cool down or heat up. Î...

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.
