  • Page 7: Notes On Possible Severe Personal Injury

    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 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.
