Product Overview
The SAMSON Type 3730-3 Intelligent Digital Valve Positioner is designed for accurate positioning and automated control of pneumatic valve actuators in industrial process systems. Manufactured by SAMSON, this microprocessor-based electropneumatic positioner uses a 4–20 mA two-wire electrical signal with HART communication to regulate pneumatic output pressure. Its intelligent control technology supports precise valve positioning, stable flow regulation, and reliable industrial automation.
Part of the SAMSON Type 3730 Series, the 3730-3 features automatic initialization, an integrated LCD display, rotary pushbutton operation, and EXPERTplus valve diagnostics. It supports direct attachment to compatible SAMSON actuators, NAMUR mounting, and rotary actuator installations using suitable accessories. Its robust construction makes it suitable for oil and gas processing, chemical manufacturing, petroleum refining, power generation, and water treatment.

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.
