D971X QT type electrical butterfly valve Product introduction

D971X QT type electrical butterfly valve turns multi-turn rotational motion into partial rotational motion  through reducer by electromotor. Provided with features of starting and closing steadily, large output torque, and the labor intensity of the operator can be greatly reduced, Especial for high pressure, heavy caliber Valves; It is suitable for being installed at the place can not be manual manipulation or hard to access, the Electric wafer butterfly valves are unlimited by height of installation, easy for remote control, make for the overall system automation; power source could be obtained easier than pneumatic or hydraulic source, the establish of electric wire is simpler than pneumatic or hydraulic line. But the structure is complicated, should be taken protection against the moisture and explosion. Normally used in the environment temperature under 50℃, and the relative humidity less than 80%.

D971X QT type electrical butterfly valve Product features

● The shell of valve are fully made by die-casting aluminum and precision machine work, the quality of key parts is steady.
● The valve is with small size, light weight, adopted spraying technology to guarantee a excellent appearance quality.
