Rotex RTX-7 Smart Valve Positioner for Industrial Automation
Product Overview
The Rotex RTX-7 Smart Valve Positioner represents cutting-edge
innovation in valve automation, designed to work seamlessly with
RTX-8/RTX-9 series controllers and air solenoid valves. This
explosion-proof device delivers ±0.1% accuracy in controlling
linear/rotary actuators, supporting 4-20mA, HART, and RS485 Modbus
protocols. Engineered for hazardous environments (ATEX/IECEx
certified), it ensures safe operation in chemical plants, oil
refineries, and pharmaceutical facilities while maintaining IP66
corrosion resistance.
