Electric Volume Control Damper Valve
The air damper actuator is the in common use equipment in the breeze system. The electric control air valve can modulate the opening degree of the air valve, control the size of amount of breeze. On-off air valve play the role of close and open. If request time for close and open, you can cut off the air valve quickly, and the time of total travel can be finished in 6 seconds or 3 seconds.
Damper is commonly used equipment in air supply system, electric control damper is composed of electric actuators and damper. Regulated electric damper can control the opening of valve and the size of volume.
Model:
DZF is composed of DKJ series actuator and DF air valve.
SHZF is composed of SH series actuator and DF air valve.
SKJZF is composed of high speed actuator and DF air valve.
Electric control air damper is divided into quadrate and round:
The quadrate is DF-F type long * wide is 160*130---1000*500
The round is DF-Y type DN100---DN1400
Connection Type between Damper with Actuator
1. If the size of air valve of the actuator is bigger, it's volume and weight are also bigger. If adopt the direct-mounted model.
2. In many ways are all inconvenient on mounting, maintaining and using various, you can adopt foot-plate mounted model actuator. Mount air valve and actuator separately, the actuator is fixed on one foundation even on the stage and connected with the live axle of air valve through ball-joint.
