Product Overview
The SAMSON 3241 / 3271 / 3730-3 is a high-performance pneumatic globe control valve assembly engineered for precise throttling and on/off control of process fluids in industrial pipelines. The system combines a SAMSON Type 3241 or Type 3271 globe valve body with the Type 3730-3 electropneumatic valve positioner, forming a complete closed-loop control unit. The valve operates on a pneumatic diaphragm actuator principle, where a signal pressure from the positioner modulates the plug position relative to the seat to achieve accurate flow regulation. The Type 3730-3 positioner provides advanced digital communication capabilities, including HART protocol, enabling seamless integration with modern distributed control systems (DCS). This assembly is widely deployed in process industries requiring reliable pressure, temperature, flow, and level control of steam, gases, and liquids.
