Motorized Damper Actuator (Square,Round and Louver Type)
Motorized Dampers function as open-close part in the rotating circular butterfly disc with valve stem, could achieve the opening and closing of the valve. Butterfly valves for shut-off valve can also be designed to make regulation and truncation.
Used for throttling or shutting off the flow of corrosive or non corrosive gases, liquids and semi liquid. It can installed in any selected position in pipelines in the industries of petroleum processing, chemicals, food, medicine, textile, paper making, hydroelectricity engineering, building, water supply and sewage, metallurgy, energy engineering as well as light industry. Apply to the breeze system in the boiler, and higher temperature.
Apply to the breeze system in the boiler, and higher temperature. We could provide you the specification according to the size of pipe, divided into quadrate damper valve and round damper valve.
The damper valve is the common equipment in the breeze system, the electric damper valve is composed of actuator and damper valve. The modulating automatic damper valve can modulate the opening degree of the damper valve, control the size of amount of breeze. On-off damper valve play the role of close and open. If request the time for close and open, you can cut off the damper valve quickly, and the time of total travel can be finished in 6 seconds or 3 seconds.
The type as follows:
DZF is composed of DKJ series actuator and DF damper valve.
SHZF is composed of SH series actuator and DF damper valve.
SKJZF is composed of high speed actuator and DF damper valve.
Damper valve 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
The actuator which is mounted the damper valve directly called direct-mounted model.
If the size of damper valve of the actuator is bigger, it’s volume and weight are also bigger. If adopt the direct-mounted model, in many ways are all inconvenient on mounting, maintaining and using various, you can adopt foot-plate mounted model actuator. Mount damper valve and actuator separately, the actuator is fixed on one foundation even on the stage and connected with the live axle of damper valve through ball-joint.
