ABB V18345-1010521001
The ABB V18345-1010521001, or ABB TZIDC Electropneumatic valve posifier, is an intelligent instrument for precise control of valve opening. By receiving a standard 4-20mA signal from the control system, it drives the valve actuator to achieve precise regulation of fluid flow, pressure or temperature. Widely used in petrochemical, electric power, water treatment and other industrial fields.
