Product Overview
The SAMSON 3241 / 3277 / 3730-2 is a high-precision pneumatic globe control valve assembly engineered for demanding process control applications. Manufactured by SAMSON AG, a global leader in control valve technology, this assembly combines a Type 3241 globe valve body, a Type 3277 pneumatic diaphragm actuator, and a Type 3730-2 digital electropneumatic positioner. The valve operates on a linear globe valve principle, where a plug stem modulates flow through a contoured seat to precisely regulate pressure, flow rate, temperature, or level in industrial process loops. The integrated Type 3730-2 positioner provides accurate stem positioning via a 4–20 mA input signal, ensuring tight control, fast response, and reliable performance in continuous process operations.
