Motorized valve actuator DY series

90°IP67ISO

DIAMANT DC ACTUATOR ISO 5211 CONNECTION HEATING / COOLING / INDUSTRIAL USE 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 Diamant: 12V DC and Diamant: 24V DC motorized valves are used with direct current suppty. An important (eature is the ablllty to reach high pick-up torques and very fast opera-ting tlmes. In particular. they are widety used for regulating and interceptmg 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 The figures show the wihng diagram of the actuator with a 2-POINT ON/OFF controt device. The wiring diagram is shown open and closed. respectively. Supplying power voltage across terminal 2 closes the valve (electrical auto-matic closing): supplying power across terminal 3. too. opens the valve. terminal 1 : négative polarity (DC) or phase 1 (AC); terminal 2: positive polarity (DC) or phase 2 (AC) for closing; terminal 3: positive polarity (DC) or phase 2 (AC) for opening.
