  • Page 5: Safety Instructions And Measures

    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 (see associated actuator documentation). When the valve is combined with one of the following SAMSON actuators, the valve moves to a certain fail-safe position (see the 'Design and principle of operation' section) upon supply air or control signal failure.
  • Page 7 Safety instructions and measures Responsibilities of the operator The operator is responsible for proper operation and compliance with the safety regulations. Operators are obliged to provide these mounting and operating instructions as well as the referenced documents to the operating personnel and to instruct them in proper operation. Furthermore, the operator must ensure that operating personnel or third persons are not ex- posed to any danger.

    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. Impermissible pressure or improper opening can lead to valve components bursting. Î Observe the maximum permissible pressure for valve and plant. Î...
  • Page 9 Î Wear eye protection when working in close proximity to the control valve. 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. Î Before starting any work on the actuator, relieve the compression from the preload- ed springs (see associated actuator documentation).
