  • 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' chapter) upon supply air or control signal failure.
  • Page 7 Start-up and shutdown procedures fall within the scope of the operator's duties and, as such, are not part of these mounting and operating instructions. SAMSON is unable to make any statements about these procedures since the operative details (e.g. differential pressures and temperatures) vary in each individual case and are only known to the operator.

    − When a substance is used in the device, which is listed as being a substance of very high concern on the candidate list of the REACH regulation: Information on safe use of the part affected u www.samsongroup.com > About SAMSON > Environment, Social & Governance > Material Compliance > REACH − If a device contains a substance listed as a substance of very high concern on the candi- date list of the REACH regulation, this is indicated on the SAMSON delivery note.

  • Page 9: Notes On Possible Personal Injury

    Î Only use protective equipment that can be protected against unintentional recon- nection of the power supply. Î SAMSON electric actuators are protected against spray water. Avoid jets of water. Î Observe all other safety instructions in the associated documentation of the electric device (e.g.
  • Page 10 Î Wear eye protection when working in close proximity to the control valve. Risk of personal injury due to preloaded springs in pneumatic actuators. 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).

  • Page 11: Notes On Possible Property Damage

    Safety instructions and measures WARNING Risk of personal injury due to residual process medium in the valve. While working on the valve, residual medium can flow out of the valve and, depending on its properties, cause personal injury, e.g. (chemical) burns. Î If possible, drain the process medium from the plant sections affected and from the valve.
  • Page 12 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 surfaces.
