EV260B Servo-Operated 2-Way Proportional Solenoid Valve
Brand: DanfossEV260B is a proportional (modulating) servo-operated 2-way solenoid valve with connections from 1/4" to 3/4".
Through stepless regulation of the coil current, the armature can be placed in any position in the armature tube, thus setting the valve to any position between completely closed and completely open.
The valve is fully open when the coil current has reached its maximum value.
Features- For water, oil and similar neutral liquids
