| 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. |
