The Samson 3241 globe control valve regulates process flow by moving a linear plug within the valve body. As the actuator responds to the control signal, the valve stem moves the plug relative to the seat, adjusting the flow area. When equipped with a valve positioner, the valve achieves precise positioning, fast response, and consistent control performance.

• Install the valve according to flow direction marking
• Mount the actuator and valve positioner
• Connect control signal and instrument air supply
• Perform calibration and stroke testing
• Verify valve operation under process conditions
