Motorized valve actuator CY series

90°IP67ISO

AC/DC supply with 2 extra micro switches ALL-IN-ONE actuator for 3 points without relay or 2 points with relay connection ISO 5211 connection F03-F05 q 9-11 The figures show the wiring diagram of the actuator with 2-POINT ON/OFF control device. The wiring diagram is shown open and closed. respectively. Supplying power by means of a phase across terminal 2 causes the valve to close (electrical automatic closing); supplying power across terminal 3. too. causes the valve to open. The figures show the wihng diagram of the actuator with 3-POINT ON/OFF control device. The wiring diagram is shown open and closed. respectively. When the phase flows across terminal 3. the valve opens: on the contrary. when the phase flows across terminal 2. the valve closes. The phase can be diverted to terminal 2. terminal 3 or to none of them. in order to obtain partial openings of the valve. This is necessary for modulatmg the flow when a régulation is needed. Each actuator must be operated by a single electric control.
