Frequency Electric butterfly valve suitable for medium to water, water, pump oil export pipeline, through the inverter and PLC electrical system, electric control valve device is open, fast close, buffer closing speed to achieve the pipeline reliable cut-off, effectively eliminating Water Hammer, multi-faceted to meet the different channels of different systems and the same valve opening and closing stages of valve opening and closing speed.
Frequency Electric butterfly valve with the novel design and reasonable structure, light, simply adjust the soft processes that can achieve a variety of speed, make full use of resources, greatly expands the scope of application of electric valve. And for pump control valve, then remove the other electro-hydraulic valve linkage class of potential leakage of hydraulic oil pollution, to protect the health of the working environment clean, environmentally friendly theme of the eternal.
The electric control valve actuator motor through the inverter to adjust the input frequency, so that the output to achieve infinitely variable, PLC for logic operation, simple operation, reliable performance, high intelligence, fully meet the needs of users automated control.

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.
