Jiangsu Lan valve ZB-type valve actuators can be used to make a 90 degree rotation of the valve plate valves, such as butterfly valves, dampers and so on. Flameproof electric valve actuators rated working voltage of the main technical parameters: 380,660V rated power frequency: 50HZ Rated control current: ≤15A Rated control voltage: AC: 6V 9V 12V 24V 36V DC:. 6V 9V 12V 24V 36V TTL Power level signal: 5V 24V signal input impedance: ≤150Ω signal output impedance: ≤700Ω maximum signal current: 36mA (output) Ambient temperature: -20 + 40 ℃ Relative humidity: ≤95% (25 ℃ when) proof mark: Ex dI Mb protection: IP55 surrounding medium: containing gas, methane and coal dust and other explosive mixture valve actuator, no damage to the insulation of single-gas environment. (Except for the mining face) 江苏兰 valve General Equipment Co. manufacturing KXBC flameproof electric valve actuators control box for explosive environments (coal, chemical, oil. Power industries) actuator structure, the safety factor high operating functions, stable performance. KXBC flameproof electric valve actuators control box Technical Performance: 1. with a variety of short circuit protection, phase failure, overload, voltage, leakage, etc; 2. to provide remote / local two options; 3. Signal level: DC5V, DC24V; 4. output impedance ≤700Ω; 5. Maximum output signal current DC36 mA; 6. After the motor rotation to determine the actuator valve, automatically correcting the phase sequence of three-phase power actuators, users can easily access to electric The three-phase power control box; 7. reliable automatic control system with a variety of convergence; 7.1 provide a dry contact by the user, + 24VDC power usage module (see electrical schematics); 7.2 + 24VDC power supply provided by the user at this time Users of + 24VDC power supply negative and negative power supply module and connected together, the positive input power to the end of each function module, you can achieve a variety of control functions; 5.8 input / output signals were confirmed by optical isolation, anti-interference ability; 5.9 open valve, close the valve, electronic interlocking plus mechanical interlock, reliable guarantee to open and close the AC contactor can not pull; 5.10 minus 15% of rated voltage undervoltage protection value. _ 江苏兰 valve actuators role (certified) _ 江苏兰 valve actuator is provided by General Equipment Co., Ltd ..
