SAMSON
Official website: www.samsongroup.com ↗SAMSON, founded in 1907 in Frankfurt, is one of the few control valve makers that owns its entire actuation stack: bodies, pneumatic actuators, positioners and even the control-thermometer business. That vertical integration shows in the catalogue — a Type 3241 globe, a Type 3271/3277 actuator and a 3730-series positioner are engineered as one system, which simplifies sizing accountability and spares logistics.
The Type 3241 is the European workhorse globe: simple, robust, configurable from standard to balanced-trim severe duty, and mirrored by a wide self-operated regulator programme for pressure, temperature and differential-pressure control without instrument air. In district energy, chemical plants and HVAC-adjacent process duty across Europe, SAMSON is often the default specification, and its documentation discipline — data sheets per type, EN-based sizing — fits European procurement habits.
