12V DC and. motorized valves are used with direct current supply. In particular, they are widely used for regulating and intercepting fluids in: automation systems on watercrafts automation systems on civil and industrial vehicles industrial systems in general using hot and cold fluids Systems using alternative energy automation systems in general zootechnical systems TECHNICAL FEATURES Electric control Operation (see also the Electrical connections section) Connection with valve body Compatible valve bodies (Please see Compact PRO technical data sheet for body valves that can be combined) Motor Power supply Electrical connection Operating time ( 90°) and relative rated torque (for a 180° operation, double the provided times) * Nominal torque absorption (standard version) Overcurrent protection bidirectional DC 24 V DC/AC 12 V DC/AC by means of a terminal block inside the actuator 30 seconds • 22 Nm 10 seconds • 22 Nm 0,4 A 0,25 A extra-fast acting fuse Maximum current tolerated by extra microswitches Maximum noise (at a 1 meter distance) Operational room temperature Protection degree IP67 featuring a ribbed surface, in a glass-reinforced "polyarylamide" techno-polymer, particularly strurdy and damp-proof External covering Material of external metal components Washers material AISI 303 GVR and brass CW617N silycone Type of reduction unit Maintenance Certification * for different operating times, please contact our Technical Office 90° clockwise and counter clockwise 180° clockwise and counter clockwise 2-way 3-way with switch 3-way with mixer VALVE BODIES top performance COMPARATO none EC actuators can be paired with all the ball valves described on the technical sheets. ELECTRICAL CONNECTION ONLY VERSION DC actuators can be connected to with 2 or 3 POINTS without distinction, in DIRECT current or ALTERNATING current, with no need to operate the actuator.

DC-CURRENT ACTUATORS ELECTRICAL CONNECTIONS 2-POINT CONTROL – ON/OFF (SWITCH) • terminal 1: negative polarity (DC) or phase 1 (AC); • terminal 2: positive polarity (DC) or fixed phase 2 (AC) for closing; • terminal 3: positive polarity (DC) or phase 2 (AC) for opening. La tensione al morsetto 3 può essere fornita tramite un interruttore. Più servocomandi possono essere azionati da un singolo comando elettrico.

DC-CURRENT ACTUATORS Should power fail, the actuator remains in the position it was when the power outage occurred. DC actuators feature: • an additional opening feedback microswitch (free contact) which is electrically closed when the valve is open. Example of use: notification of opening, pump relay actuation, boiler control, notification to PLC, etc. • an additional closinsg feedback microswitch (free contact) which is electrically closed when the valve is closed. Example of use: notification of closing, relay actuation, notification to PLC, etc. The layout of the additional microswitch contacts...

DC-CURRENT ACTUATORS The valve should be installed in such a way that the actuator connection is not facing down. When the valve works with low-temperature fluids (possible frost formation on the valve stem) or with high-temperature fluids (danger of actuator overheating), it is advisable to install it in the recommended position, as shown in the picture.
