Ball valve UY2 series

electrically-actuatedfor controlPVC

ALL-IN-ONE actuator for 3 points without relay or 2 points with relay connection Operating time: 55 sec for 90° rotation – 40Nm Protected type, manual emergency override, 2 extra micro switches Available with threaded or to-be-glued connections ACCESSORIES ON REQUEST • - Insulation spacers with and without manual opening (see "Valve bodies" section). • - Anti-condensation résistance, for preventing the risk of condensation inside the actuator. • - 60 Hz version. • - terminal 1: neutral; • - terminal 2: fixed closing phase; • - terminal 3; opening phase. The phase to terminal 3 can be supplied by means of a switch. One electrlc control can actlvate several actuators. 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.
