D9bs41X(H)频率转换速度modulatio

D9bs41X(H) frequency conversion velocity modulation reed valve VVVF electric butterfly valve for medium to water, seawater, oil pump outlet tube on the road, through the inverter and PLC electrical systems, effective control of electrical devices that valve to open, fast turn off, turn off the speed of the buffer, the pipeline implementation reliable cut-off, the effective elimination of pipeline water hammer, multi-directional pipeline system, as well as meet the needs of different valves different headstock the same stage of the valve gate speed requirements. VVVF electric butterfly novel, rational design, structure, light weight, simply adjust the soft procedures that can achieve a wide range of variable speed to ensure full utilization of resources, greatly expanded the scope of application of electric butterfly valve. And when used as a pumping station control valves and to eliminate other types of electro-hydraulic valve linkage possible leakage of hydraulic oil pollution, the protection of the working environment of cleanliness and sanitation, in line with the timeless theme of environmental protection. The electric control valve through the inverter to the motor drive input frequency adjusted to achieve non-polar output speed, the use of PLC for logic operation, simple operation, reliable performance, intelligent high degree of automation and control fully meet user needs.
