    Therefore, operators must ensure that the devices 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 applications or conditions other than those 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 Components of the device that differ to those used for the standard version described in this document can be exchanged with other certain SAMSON components. The residual hazards of these components are described in the associated mounting and operating instructions (see documents listed under 'Referenced documentation'). Safety features The Type 2375 Regulator does not have any special safety features. When relieved of pres- sure, the regulator is closed by the force of the set point springs. EB 2536 EN...
  • 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 8: Notes On Possible Severe Personal Injury

    Safety instructions and measures 1.1 Notes on possible severe personal injury DANGER Risk of bursting in pressure equipment. Regulators and pipelines are pressure equipment. Improper opening can lead to regula- tor components bursting. Î Before starting any work on the regulator, depressurize all plant sections affected as well as the regulator. Î Drain the process medium from all the plant sections affected as well as the regula- tor.

  • Page 9: Notes On Possible Property Damage

    Î Wear protective clothing and safety gloves. Damage to health relating to the REACH regulation. If a SAMSON device contains a substance listed as a substance of very high concern on the candidate list of the REACH regulation, this is indicated on the SAMSON delivery note.
  • Page 10 Risk of regulator damage due to the use of unsuitable sealants or lubricants. The sealants and lubricants to be used depend on the regulator material. Unsuitable sealants and lubricants may corrode and damage surfaces. Î Only use sealants and lubricants approved by SAMSON (see section 7.3). Incorrect control due to the formation of ice on the regulator. Medium temperatures below 0 °C may cause ice to form on the regulator, depending on the air humidity.
