Intended use
The Type 3381 Silencer acts as a fixed restriction to reduce the sound pressure level. It is de -
signed for mounting on SAMSON Series 240 and Series 250 Control Valves. The silencer is
used to reduce the noise of liquids, gases and vapors as they flow through the valve and to
reduce the velocity of compressible media (e.g. gases and vapors) at the valve outlet.
The silencer is designed to operate under exactly defined conditions (e.g. operating pressure,
process medium, temperature). Therefore, operators must ensure that the silencer is only used
in operating conditions that meet the specifications used for sizing at the ordering stage. In
case operators intend to use the silencer 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.
Reasonably foreseeable misuse
The silencer is not suitable for the following applications:
− Velocity reduction of incompressible media
− Use outside the limits defined during sizing and by the technical data
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described
Qualifications of operating personnel
The silencer must be mounted, started up, serviced and repaired by fully trained and quali-
fied personnel only; the accepted industry codes and practices must be observed. According
to these mounting and operating instructions, trained personnel refers to individuals who are
able to judge the work they are assigned to and recognize possible hazards due to their spe -
cialized training, their knowledge and experience as well as their knowledge of the applica -
ble standards.
Welding operations must only be performed by personnel who has the necessary qualifica -
tion to perform the applied welding procedure and handle the materials used.
