Product overview

The manual (electric) butterfly type cold air release valve is composed of a valve body, a butterfly plate, a connecting rod, a muffler, an exhaust duct and other components. The manual lever mechanism or electric device is used to turn the disc to open and close the valve, so as to reduce or completely stop the air supply to the blast furnace without stopping the blower, and the excess gas is discharged to the atmosphere. The special place in its structure is the electric drive that can be operated from a distance. Moving the size of the disc of the vent valve can easily change the size of the air volume, and the output signal is reversed through the automatic position on the vent valve. Use DFP-09 electric operator to display the size of valve opening. As long as the electric operator is controlled, the required air volume can be achieved. It is suitable for ventilation ducts in building materials, metallurgy, chemical industry, power station and other industries, as a device to automatically adjust or remotely control the air volume required by equipment.
