D971X explosion-proof soft seal electric butterfly valve features:
1, the shell: the shell is hard aluminum alloy, the anodic oxidation treatment and polyester powder coating, strong corrosion resistance, protection class is IP67.
2. Motor: Fully enclosed squirrel-cage motor, small size, large torque, small inertia force, F insulation class, built-in thermal protection switch, can prevent damage to the motor.
3, manual structure: handwheel design to ensure safe and reliable, labor saving, small volume. No power, pull the clutch handle can be manually operated. When energized, the clutch automatically resets.
4, indicator: The indicator is installed on the central shaft, you can observe the valve position. The convex lens design, no water, more convenient observation.
5, dryer: used to control humidity, to prevent the internal moisture condensation due to temperature and weather changes in the actuator, to keep the internal electrical components dry.
6, limit switch: mechanical, electronic double limit. Mechanical limit screw adjustable, safe and reliable; The electronic limit switch is controlled by the CAM mechanism, the simple adjusting mechanism can set the position accurately and conveniently, and is not affected by the excessive hand wheel.
7, the torque switch: can provide overload protection (except FH-010), prevent damage to the motor. (It has been set before delivery, please do not change the Settings at will).
8, self-locking: precision worm gear and worm mechanism can be efficient transmission of large torque, high efficiency, low noise (maximum 50 decibels), long life with self-locking function, prevent inversion, transmission part stable and reliable part stable and reliable, no need to refuel.
9. Anti-stripping bolt: When removing the shell, the bolt is attached to the shell and will not fall off.
10, installation: the bottom installation size in line with ISO5211 international standards, drive shaft sleeve can be removed according to the need for processing, strong adaptability. It can be installed vertically or horizontally.
