DDF series electric butterfly valve is a control valve composed of an electric actuator with an angular stroke and a butterfly valve body. It is mainly suitable for air-conditioning, heating and other building automatic control systems.
● DDF electric butterfly valve comes with beautiful appearance, compact structure, small size and light weight, and it is easy to install, disassemble and maintain.
● Quick opening and closing of 90 ° rotation and good adjustment performance.
● The butterfly plates on both sides of the rotating shaft are affected by similar force, and the direction of the torque is opposite, so the opening and closing torque is small and more energy-saving.
● Good low-pressure sealing performance
● Low fluid resistance
● Powerful function: this control valve comes with a variety of control signals and feedback signals for selection.
● Integrated design of worm gear output shaft provides high transmission accuracy.
● Safe and reliable: the series valve has passed the AC1500V withstand voltage test and selects F-class insulated motor.
● The number of startup and shutdown is no less than 60,000 times.
● IP65 high standard protection level
