SAMSON 3241/3374 Motorized Control Valve PN40 DN20
Achieve millimeter-accurate modulation and long-lasting performance in high-pressure process lines.
The SAMSON 3241/3374 Motorized Control Valve is engineered for precise flow and pressure management in industrial plants. In addition, its PN40 pressure class and DN20 nominal diameter ensure safe operation under heavy industrial conditions. In particular, the Type 3241 globe body provides superior stability during fluid modulation.
Moreover, the Type 3374 electric actuator responds instantly to 4–20 mA or 0–10V control signals. The valve body is available in GG-25 or GGG-40 cast iron, offering corrosion resistance. Furthermore, it operates across a wide temperature range from -10°C to +350°C, which benefits steam and superheated water lines. Consequently, the metal-metal or soft-seat sealing design delivers a high shut-off class according to DIN EN 1349.
