Butterfly valve is usually used for fluid with large flow and low drop-out. It is small in size, low in cost. Its installation space is small, and structure simple. Matched with electric actuator, it can be adjusted by computer signal.
Electric Adjusting Butterfly Valve
According to the requirements of manufacturing technique, butterfly valve has many types: midline double-clip type, light type, corrosive-proof fully-lined type, and three-eccentric center type that has good seal effect and cutting off function, and air butterfly valve used for gas regulation. Quarter-turn electric actuator has DKJ series, which design products for the country uniformly; and SD series nationalized electric actuator introduced from French Bernard products.
On-off butterfly valve can also be equipped with QT series and 802 series electric valve actuator. The flow characteristic of butterfly valve is approximate to equal percent. The opening angle of the above butterfly valves is 90°. Its rated KV figure surpasses that of other valves of the same caliber greatly.
Electric adjusting butterfly valve can be divided into electric midline double-clip adjusting butterfly valve, electric flange fully-lined adjusting butterfly valve, and electric three-eccentric center medal seal adjusting butterfly valve, electric air adjusting butterfly valve, etc. The types will not be listed one by one here in the technology note.
