A hand electric closed valve use: D940J-0.5 manual electric dual-sealed valve for switching the ventilation mode, change the air flow for air defense, national defense and civilian industries drive medium ventilation and air exhaust piping. The valves are suitable nominal PN≤0.05MPa, operating temperature - 30 ~ + 40 ℃, relative humidity of 30 to 90%, the medium is the air pipeline, as the one-way closed-circuit mechanism. Hand electric closed valve has anti shock and pressure capability, dual electric and manual, note should be consistent with the medium flow direction of the arrow marked on the valve body when installing. Second, hand electric closed valve technical parameters and performance hand electric closed valve actuators technical parameters D940J hand electric closed valve body parameters Power AC110,220,380V / DC24,220V nominal diameter DN150 ~ 1000mm output torque 50N · M ~ 2000N · M Nominal PN0.05MPa optional functions switching, contact type, opening signal, intelligent valve shaft material Carbon operating range 0 ~ 90 ° ± 5 ° Body material ductile iron, carbon steel operation time of 15 seconds / 30 seconds / 60 seconds the valve plate material ductile iron, carbon steel ambient temperature -30 ° ~ 60 ° seat sealing NBR manual supplied with the operating handle in the form of a linear structure limit electrical, mechanical double protection limit temperature NBR≤68 ℃ grade IP-67 (explosion-proof enclosure: Exd Ⅱ BT4 IP67 optional) For medium air input signal 0-10,1-5VDC / 4-20mA (Smart) Features remote control, opening and closing flexible, compact three structures, hand electric closed Valve size Nominal diameter DN ABD D1 L Nominal power Nominal current 150 155 320 166 195 92 15W 0.2A 200 155 450 215 250 118 15W 0.2A 250 155 472 260 320 130 15W 0.2A 300 155 500 315 360 145 15W 0.2A 400 208 556 441 490 175 25W 0.5A 500 208 622 560 622 225 25W 0.5A 600 208 764 666 720 275 25W 0.5A 700 256 806 770 820 290 50W 0.8A 800 256 866 870 920 290 50W 0.8A 900 256 900 960 1010 290 90W 1.0A 1000 288 1005 1090 1160 300 120W 1.2A four hand electric closed valve installed a hand electric closed valves can be installed in horizontal or vertical pipes, requires the use of the valve plate full open or fully closed, can not be adjusted with the flow. 2, hand electric closed valve installation, you should ensure pressure bore signs of haircut that is consistent with the direction of the shock wave, and should facilitate the operation of the valve handle. 3, hand electric closed valve can be installed in the form of supports or hangers. 4, hand power to take over the closed valve flange and rubber gasket Click to processing. Five hand electric closed valve Note: 1: sure to connect the power supply phase sequence, so that the valve or actuator damage. 2: power to prohibit manual operation. 3: outdoor use best protection is applied to the electric actuator cover, to prevent aging. 4: After opening the cover should tighten the screws to prevent water or dust from entering the electric actuator inside. 5: Do not install in an explosive gas around, please specify when ordering For proof. 6: Make sure the input voltage and the wiring contacts are correct. 7: Do not overload electric actuators.
