Product Descriptions
DC12v intelligent air outlet grille, the front part is AV (H) tuyere, the rear part is OHD electric regulating valve, is a relatively common air supply outlet (pipe air supply and indoor central air conditioning). OHD electric regulator can be used with ASD, suitable for high space. It is suitable for underground air supply air conditioning and rain proof louver. It can be opened freely, (ventilated at ordinary times) and closed freely (cold air is prevented from entering the room in winter).
The outer frame and blade of the electric control valve are of 6063T type, and the blade is closely connected with the gear. The motor gear and blade gear bite to drive the blade to open and close. It overcomes the shortcoming that the torque of opening and closing points should be large when the old products move in parallel. It has the characteristics of smooth switch, low noise, large air output, and can be adjusted at will.
