Manual and electric leafy folio regulator is installed in the air ducts of the ventilation system meeting ventilation requirements, used to adjust the air volume, control wind speed .

1.Mainly made by the valve body, valve leaf, shaft and bushing, actuators.

2.Body and blades are all made of high quality galvanized steel manufacturing, with a beautiful appearance, good anticorrosion performance, product advantages of long use.

3.The combination of the valve adopts the most advanced technology for sheet metal connection - TOX without welds connection technique.

4.Blade design and the axis of rotation into v-shaped antiskid structure, ensures that the blade under the condition of high speed sliding, loose.

5.Blades rotate bearing and connecting rod bearing adopt oil powder metallurgy copper collar, the unit must refueling, ensure permanent lubrication.

6.Actuator adopts the static design of micropower, in most of the time in standby state (sleep), its standby when the measured power only 0.5 w, so greatly save the energy consumption.

7.Electric open or close the valve, the output signals.A manual button, can be manually open or close, form of connection plate for flange or Angle steel flange connection.

8.Also can use stainless steel material.
