Intended use
The SAMSON Type 3291 Globe Valve in combination with an actuator (e.g. Type 3271 or
Type 3277 Pneumatic Actuator) is designed to regulate the flow rate, pressure or temperature
of liquids, gases or vapors. The valve with its actuator is designed to operate under exactly
defined conditions (e.g. operating pressure, process medium, temperature). Therefore, opera-
tors must ensure that the control valve is only used in operating conditions that meet the spec -
ifications used for sizing the valve at the ordering stage. In case operators intend to use the
control valve 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.
