1 Safety instructions and measures
Intended use
The Type3310 Segmented Ball Valve combined with an actuator, e.g. a SAMSON
Type3278 Pneumatic Rotary Actuator or an AIRTORQUE TypeSRP/DAP Pneumatic Rotary
Actuator is designed for both throttling and on/off service. The control valve is suitable for
liquids, vapors and gases.
The valve with its actuator is designed to operate under exactly dened conditions (e.g.
operating pressure, process medium, temperature). Therefore, operators must ensure that the
control valve is only used in operating conditions that meet the specications used for sizing
the valve at the ordering stage. In case operators intend to use the control valve in other
applications or conditions than specied, 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 elds of application as well as
possible uses.
Reasonably foreseeable misuse
The control valve is not suitable for the following applications:
− Use outside the limits dened during sizing and by the technical data
− Use outside the limits dened by the valve accessories connected to the valve
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described
Qualicationsofoperatingpersonnel
The control valve must be mounted, started up, serviced and repaired by fully trained and
qualied 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 specialized training, their knowledge and experience as well as their
knowledge of the applicable standards.
