Product Overview
The SAMSON 3730-31001000400000009.04 Intelligent Digital Valve Positioner is designed for precise positioning and automated control of pneumatic valve actuators in industrial process systems. Manufactured by SAMSON, this electropneumatic positioner uses a standard 4–20 mA electrical input signal with HART digital communication to regulate pneumatic output pressure and maintain accurate valve positioning. Its microprocessor-based control system continuously compares the required valve position with actual actuator travel, providing responsive valve movement, stable flow regulation, and dependable process control.
Part of the SAMSON Type 3730-3 Series, the 3730-31001000400000009.04 features automatic calibration, integrated EXPERTplus diagnostics, an LCD display, and an analogue position transmitter for independent 4–20 mA valve travel feedback. Its aluminium housing provides IP66/NEMA 4X enclosure protection, while its intrinsically safe ATEX configuration supports suitable hazardous-area installations. With HART communication, adjustable valve characteristics, and flexible mounting arrangements, this positioner is suitable for oil and gas processing, chemical manufacturing, 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.
