Product Overview
The SAMSON 3730-2100100040000000.04 Smart Electropneumatic Valve Positioner is designed for accurate positioning and automated control of pneumatic valve actuators in industrial process systems. Part of the SAMSON Series 3730, this intelligent positioner operates using a standard 4–20 mA electrical control signal to regulate pneumatic output pressure and maintain precise valve positioning. Its microprocessor-based control technology supports responsive actuator movement, stable flow regulation, and reliable performance in industrial environments requiring consistent process control.
The SAMSON Type 3730-2 features automatic initialisation, an integrated LCD display, configurable control characteristics, and advanced diagnostic functions for convenient operation and maintenance. Its electropneumatic design combines an electronic control unit, current-to-pressure converter, and pneumatic air capacity booster to deliver accurate actuator control. Unlike the HART-enabled Type 3730-3, the Type 3730-2 uses local configuration and SAMSON's serial communication interface. Its versatile mounting options make it suitable for pneumatic linear and rotary actuators used in manufacturing, chemical processing, oil and gas facilities, power generation, and industrial fluid control applications.

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.
