Product Overview
The SAMSON 3730-5 Electropneumatic Valve Positioner is designed for precise positioning and automated control of pneumatic control valves in industrial process applications. Part of the SAMSON Series 3730, this intelligent positioner uses microprocessor-controlled technology to regulate valve movement by comparing the control signal received through a FOUNDATION Fieldbus network with the actual valve position. It delivers accurate pneumatic output adjustments, helping maintain stable process conditions, efficient flow regulation, and reliable industrial equipment performance.
Engineered for demanding industrial environments, the SAMSON 3730-5 supports both linear and rotary pneumatic actuators, making it suitable for a wide range of automated valve assemblies. Its automatic initialisation, integrated LCD display, digital communication capabilities, and advanced diagnostic functions simplify commissioning, operation, and maintenance. The positioner supports FOUNDATION Fieldbus communication, while HART communication is available on other models, including the SAMSON 3730-3. Other related SAMSON positioner models include the 3725 and 4763, which offer different control configurations and operating characteristics.

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.
