Profibus Electric Multi Turn Control Valve Actuator In Power Plant Partial Rotary

Power Plants Special Intelligent Electric Actuator QB, DQ Series Partial Rotary Valve Electric Actuator

Product Overview:

1. Partial rotary valve electric device is used for partially rotating valve discs, such as ball valves, butterfly valves, air doors, etc.
2. Some of our company's rotary valve electric devices are divided into two series: QB and stacked DQ products. The torque range of QB series is 125~4000N · m (adjustable type is 50~2000N · m); The torque range of the stacked DQ series is 2000~250000N · m (adjustable type is 4000~80000 N · m); These two series of products are divided into three types based on the different electrical control methods: ordinary type, integral type, and regulating type.
3. Ordinary valve electric devices are equipped with basic control units such as stroke and torque, and require a separate control box to achieve on-site and remote control operations of the valve. The performance indicators meet the requirements of GB/T24923-2010 "Technical Conditions for Ordinary Valve Electric Devices".
4. In addition to the basic control units such as stroke and torque, the integral valve electric device is also equipped with control modules and AC contactors and other control components. It can be directly connected to the power supply to achieve on-site operation of the valve, and can directly receive the switch signal output by the DCS control system to achieve remote control operation of the valve. The performance indicators meet the requirements of GB/T24923-2010 "Technical Conditions for Ordinary Valve Electric Devices".
5. The regulating valve electric device is suitable for closed-loop control systems in industrial processes, and can accurately position the valve by receiving a current signal of 4~40mA from the control system. The performance indicators meet the requirements of JB/T8219-2016 "Ordinary and Intelligent Electric actuators for Industrial Process Control Systems".

Notices:
1. Only qualified personnel can have the authorization to operate these equipment
2. While above mentioned personnel is using the equipment, the relevant instruction manual and/or other product files should be always prepared in a way to make the requirements of this manual be followed
3. Before the power is on, please double check the input voltage, frequency and connections are right. Any motor damage caused by wrong wire sequence or wrong voltage, the manufacturer will not be responsible for the maintenance and replacement.
4. The connection bolts for connecting valves should not be less than Class 8.8.
5. The Electric cabinet cap and motor etc. sealing area should not be opened during cloudy or rainy days.
6. Special motor was used for the electric actuator, the lasting time is short. Continuous working time should not be over the limit specified on the nameplate.
7. While the equipment is not usually used, it should be checked, maintained and activated on a regular basis. The recommend frequency is 1 time/month, and the duration should be less than 10 mins.
8. Electric related caps should not be removed at explosive environment while there is still electricity. Whenever someone want to open the electric cabinet cap, the power should be cut off.
9. The electric actuator should be stored inside a room with clean and dry condition prior to installation. If installed outside the room, it should be kept at a certain height away from the ground, and anti-humidity, anti-rain procedures should be performed.
10. While initial electric operation after installation or re-installation is required, the valve should be in the middle position to check the open/close direction. Tests should be performed one by one according to the commissioning procedure and all parts should be checked at normal status prior to using.
