Description
Samson Steam Control Valve Samson Electropneumatic Valve Positioner 3725 3730-3 3730-5
Product Overview
  1. Original Samson electropneumatic valve positioner series, perfectly matched with Samson steam control valves for precise process regulation
  2. Includes basic analog type 3725 and smart HART-enabled 3730-3 / 3730-5, covering entry-level to high-end control demands
  3. Modular structure with full range of matching valve spare parts available, easy for on-site maintenance and upgrade
Technical Specifications
Category Core Parameters
Control Performance 4-20mA input signal; 3725 accuracy ±0.5% span; 3730 series accuracy ±0.25% span; fits linear/rotary actuators
Environment & Protection IP66 enclosure; -40°C to +85°C operating temperature; optional ATEX / IECEx explosion-proof certification
Communication & Air Supply 3730 series supports HART protocol; supply pressure 1.4–6 bar; standard NPT pneumatic ports
Application Industry
  1. Petrochemical and chemical plants for steam pipeline and process fluid flow regulation
  2. Power generation and district heating for boiler steam control and heat exchange system regulation
  3. Food, pharmaceutical and water treatment for sanitary process and industrial water flow control
Common Problems & Solutions
  1. Position drift or unstable output: Recalibrate zero and span, verify clean and stable air supply pressure
  2. Slow valve response: Clean air filter element, adjust damping setting and inspect actuator air tightness
  3. HART communication failure (3730 series): Check signal wiring loop, reset communication parameters
Replacement Models
  1. Samson 3731: Upgraded smart positioner with PROFIBUS PA communication for advanced digital control
  2. Samson 3724: Basic pneumatic positioner for pure pneumatic control systems
