Jiangsu Lan valve General Equipment Co., Ltd. is located in Changzhou City Yokoyama Town. The company occupies 35,000 square meters, the plant area of ??8700 square meters, existing fixed assets 30,280,000 yuan, employees 80 people, engineering and technical staff of 15 people. Including five senior engineer. Annual production valve actuator million sets, enjoy a high honor in the industry. Intelligent electric valve actuators debugging method two position feedback · 20 mA (0%) ~ 4mA (100%) of the regulation: the actuator movement to the open position, adjust the "zero" potentiometer, discharge device, so that the two test points voltage difference of about zero (≤2mV), then adjust the "4mA" potentiometer allows the output signal is 4mA; the actuator movement to the closed position, adjust the "20mA" potentiometer allows the output signal is 20mA. Said adjustment only once finished. "Zero", "low" and "high-end" potentiometer are clockwise rotation of the output signal increases, counter-clockwise rotation of the output signal decreases, electrical equipment, such as found in a clockwise rotation of the potentiometer, the output signal reduce, Fawer Denso, set valve position potentiometer center tap outside except exchange about two lines. 2, the control field control: Press the "Live" button on the control panel, make on-site indicator light, then press the "off", "stop", "open" button to realize the actuator off, stop, start and control. Remote Control: Press the control panel "Remote Control" button, so distant lights can be controlled remotely. Jiangsu Lan valve General Equipment Co., Ltd. is located in Changzhou City Yokoyama Town. South Shanghai-Nanjing railway, the Beijing-Hangzhou Grand Canal, north of the Yangtze River and strategic location, convenient transportation, Xircom fast. Intelligent electric actuators Z series is the use of advanced modular control, the use of digital and high-definition LCD character display window, the content easy to read, big screen design allows users to easily observe the actuator valve position, torque and function observer status and settings actuators are also equipped with green, red two LED lights to indicate valve position, in place of magnetic rotary switch in the control box is completely isolated state can be converted on-site and remote control status, easily control , setting the actuator. Q series actuator includes a motor, reduction gear, field control reversing starters, Denso website with torque protection switch, travel limit switches, actuators all parts meet explosion proof requirements, in terms of product design , production, assembly, testing, we are meticulous, the better. Electrical outlets, blue valve drive (certified), Denso provided by 江苏兰 valve General Equipment Co. Jiangsu Lan valve General Equipment Co., Ltd. (www.lanfa.cn) Changzhou, Jiangsu, regulating valves leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Jiangsu Lan valve leadership with the staff warmly welcome all inquiries negotiations to create a better future for Jiangsu Lan valve.
