Oil Gas Valve Positioner Samson Control Valve 3730 Type 3730-3 3730-5 Electropneumatic 4-20MA Valve Positioner

The Samson 3730-3 is a single-acting electropneumatic positioner for linear and rotary pneumatic actuators. It converts a 4–20 mA control signal into precise pneumatic output pressure and features HART communication. It is widely used in process plants for reliable throttling control with simple local operation and automatic adaptation to the valve.
