    Therefore, operators must ensure that the regulator and actuator are only used in operating conditions that meet the specifications used for sizing the devices at the ordering stage. In case operators intend to use the devices 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. Î Refer to the technical data and nameplate for limits and fields of application as well as possible uses.
  • Page 6 Î Observe safety measures for handling the device as well as fire prevention and explosion protection measures. Safety features The Types 46-7, 47-5 and 47-1 Regulators do not have any special safety features. When relieved of pressure and with open restriction, the regulators are opened by the force of the set point springs. Responsibilities of the operator The operator is responsible for proper operation and compliance with the safety regulations.
  • 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.

  • Page 9: Notes On Possible Personal Injury

    Safety instructions and measures 1.2 Notes on possible personal injury WARNING Crush hazard arising from moving parts. The regulator contains moving parts (actuator and plug stem), which can injure hands or fingers if inserted into the valve. Î Do not insert hands or fingers between the set point springs while the regulator is in operation. Î Before performing any work on the regulator, depressurize the plant. Disconnect or shut off the external control line. Risk of personal injury through incorrect operation, use or installation as a result of information on the regulator being illegible.
  • Page 10 Î Wear protective clothing and safety gloves. Damage to health relating to the REACH regulation. If a SAMSON device contains a substance which is listed as being a substance of very high concern on the candidate list of the REACH regulation, this circumstance is indicat- ed on the SAMSON delivery note.

    Safety instructions and measures 1.3 Notes on possible property damage NOTICE Risk of regulator damage due to contamination (e.g. solid particles) in the pipeline. The plant operator is responsible for cleaning the pipelines in the plant. Î Flush the pipelines before start-up. Risk of regulator damage due to unsuitable medium properties.
  • Page 12 Î The lubricants to be used depend on the regulator material. Unsuitable lubricants may corrode and damage surfaces. Î Only use lubricants approved by SAMSON. When in doubt, consult SAMSON. Î Risk of regulator damage due to the use of unsuitable tools.
