Product Overview
The SAMSON 3241 / 3271 / 3730-2 is a high-precision pneumatic globe control valve assembly engineered for demanding process control applications. This integrated package combines a SAMSON Type 3241 or Type 3271 globe valve body with the advanced Type 3730-2 electropneumatic positioner, delivering exceptional throttling accuracy, fast response, and reliable shut-off performance. The valve operates on a pneumatic actuation principle, where a diaphragm actuator modulates the plug position in response to a control signal, enabling precise regulation of flow, pressure, temperature, or level within industrial process loops. As a core final control element in automated process systems, this assembly ensures stable, repeatable performance across a wide range of operating conditions.
