Samson 3730-3 Electropneumatic Valve Positioner & China Large
Diameter Three Way Valve Customized Control Valve
Product Overview
The Samson 3730-3 Electropneumatic Valve Positioner is a
high-precision instrument designed for pneumatic control valves,
offering precise positioning and automation in industrial
processes. Combined with China's large-diameter three-way valves,
this system provides customized solutions for complex flow control,
particularly in heat exchangers and multi-path fluid management.
The integration ensures reliable performance in demanding
environments.
Features
- Precision Control: Utilizes HART communication and a 4–20 mA input signal for
accurate valve positioning.
- Adaptability: Self-calibrates to match valve and actuator specifications,
supporting both single- and double-acting configurations.
- Durability: IP66-rated housing with Ex d certification for hazardous areas,
ensuring operation in temperatures from -20°C to 80°C.
- User-Friendly Interface: LCD display with adjustable reading direction and single-knob
menu navigation.
- Customization: Compatible with large-diameter three-way valves (DN15–150) for
heat exchanger applications.
