Product Title: SAMSON TROVIS 3730-0 Electropneumatic Valve Positioner | High-Precision Basic Control for General Industrial Applications

The SAMSON TROVIS 3730-0 is a reliable and high-performance electropneumatic valve positioner designed for essential, precise control in a wide range of industrial applications. Its core function is to accurately translate a 4-20 mA DC input control signal from your control system into a corresponding pneumatic output, ensuring the control valve’s position (the controlled variable) perfectly matches the command signal (the setpoint).

    Purchase details

This positioner is engineered for simplicity and durability. It offers straightforward installation on various pneumatic actuators using DIP switches and potentiometers for configuration, making it an excellent choice for general process control where advanced digital communication is not required. Its robust design, featuring a die-cast aluminum or optional stainless steel housing with IP66 protection, ensures reliable operation even in challenging environmental conditions.

Key Features and Benefits

  • Simple & Flexible Installation: Can be easily mounted on SAMSON direct interfaces, NAMUR flanges, or linear actuators with rod-type yokes per IEC 60534-6-1 standard. It supports any required mounting position.

  • High Control Accuracy & Reliability: Features a fast-acting analog control loop for precise adjustment without dead zones and continuous pneumatic output. The calibrated travel sensor is not subject to wear from mechanical gearing, ensuring long-term stability.

  • Energy Efficient Operation: Maintains low steady-state air consumption of approximately 110 ln/h, independent of supply and output pressure, reducing operational costs.

  • Enhanced Safety Functions: Equipped with configurable features via DIP switches, including adjustable output pressure limits, a tight-closing function, and selectable fail-safe positions for increased process safety. It is designed to prevent pulsating pneumatic output in case of actuator leaks.

  • Safety Instrumented Systems (SIL) Ready: Certified according to IEC 61508, making it suitable for use in Safety Instrumented Systems, supporting up to SIL 3 as a device.
