Product Overview
The SAMSON 3730-1, 3730-2, 3730-4, and 3730-310000004000000N Digital Valve Positioners are intelligent electropneumatic instruments designed for precise positioning and control of pneumatic valve actuators in industrial process systems. Manufactured by SAMSON, the Type 3730 Series combines electronic signal processing, pneumatic control technology, and automatic calibration to deliver accurate valve positioning. The series supports linear and rotary actuators, with communication and diagnostic capabilities varying by model.
The SAMSON 3730-1 provides basic digital positioning with a 4–20 mA control signal, while the 3730-2 offers expanded configuration and diagnostic functions. The 3730-4 supports PROFIBUS-PA communication, and the 3730-310000004000000N belongs to the HART-enabled 3730-3 family. These positioners feature LCD displays, rotary pushbutton operation, low steady-state air consumption, and robust industrial construction. They are suitable for oil and gas processing, chemical manufacturing, petroleum refining, power generation, water treatment, and industrial valve automation.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
