UNOX 3 Way Motorized Proportional Control Valve – 33609

UNOX 3 Way Motorized Proportional Control Valve – 33609

The UNOX 3 way motorized proportional control valve is designed for diverting and mixing water, steam, hot oil, and process fluids with high precision. Its GGG40.3 ductile iron body and PN25 pressure class ensure durability and safe operation in industrial environments.

The electric actuator enables proportional control with 4–20 mA or 0–10 VDC signals and includes feedback for reliable automation. PTFE soft sealing (Class VI) and V-pack stem sealing provide tight shut-off and long service life. The valve maintains its last position during power failure.
