Type 6223 is a servo-assisted solenoid control valve for K Vs flow rates from 1.4 to 5 m 3 /h. The variable opening of the cross-section is continually changed proportional to the standard elec-trical input signal. The characteris-tic curve of the valve is practically linear; regulation deviations are extremely low. With < 1%, the valve has a high sensitivity, due to a higher frequent pulse-width modulation. The solenoid control valve consists of the basic components of arma-ture, push-over coil and electronic control unit, and can be mounted in any position. The electronic control unit is integrated into the DIN 43650A cable plug, but can also be supplied as a standard DIN-rail mounting version.
