Product Overview
The SAMSON 3241 (Part No. 1165788) is a pneumatically actuated control valve engineered for precise throttling and on/off regulation of process media in industrial fluid control loops. Manufactured by SAMSON AG, a global leader in control valve technology, this globe-style valve combines a robust valve body with a spring-return pneumatic diaphragm actuator. The 3241 series operates on a force-balance principle, where the actuator thrust positions a contoured plug relative to the seat to modulate flow in direct response to a pneumatic control signal (typically 3–15 psi or 0.2–1.0 bar). It serves as a critical final control element in pressure, flow, temperature, and level control loops across chemical, petrochemical, and general process industries.

Engineering Features & Advantages
- Precision Throttling Control: The contoured plug and cage-guided trim deliver accurate, repeatable flow modulation across the full travel range, ensuring stable process control even under varying load conditions.
- Robust Pneumatic Actuation: The spring-return diaphragm actuator provides reliable fail-safe operation (spring closes or opens on air failure) and is optimized for low hysteresis and high positioning accuracy.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a rugged valve body and wear-resistant trim materials that extend service life and reduce maintenance downtime.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original SAMSON OEM standards, ensuring drop-in replacement without piping or mounting modifications.
- Versatile Configuration: Available in multiple body ratings, trim characteristics, and actuator orientations to suit a wide range of process media and control loop requirements.
