Electric Single-Seat Sleeve Control Valve
This electric single-seat sleeve control valve adopts sleeve cage throttling structure. Driven by electric actuator, it accepts 4-20mA signal to adjust flow, pressure and temperature of process medium. It features balanced plug design, small unbalanced force, stable operation and low noise. Widely applied in petrochemical, power, metallurgy and heating systems.
