Description

The Plastic Air Damper Valve installed in the PVC/PP piping system. Through manual operation or PLC automatic control technology, the damper can be opened and closed as required. The principle is that plastic blades are installed in the damper, and the damper is rotated by the damper actuator. , Drive the rotation of the butterfly valve blades to achieve a 90-degree turning angle to achieve the purpose of opening and closing, and has a feedback indication function. Through the pressure difference detection device, after closing the air valve, the signal is transmitted to the PLC system, so as to control the PVC fan frequency converter to reduce the speed and energy-saving operation.

The Manual Damper is made of PP/PVC material, which is resistant to acid and alkali corrosion. The working principle of the PP/PVC plastic manual air valve is the same as that of the PP/PVC electric air valve, except that the electric actuator is changed to a pneumatic actuator, and the air pipe is controlled by a third-party plate solenoid valve. The switch realizes the opening and closing of the Manual Damper.

Manual Damper is suitable for application environments with explosion-proof requirements such as chemical plants and laboratories. Used in PVC ventilation duct system, connected with PVC air duct. It is used for exhaust control of corrosive gas, corrosion resistance and acid resistance. Manual Damper have complete specifications, and are equipped with PP/PVC air ducts, elbows, tees, and reducers to form a complete PP/PVC ventilation duct system. The pneumatic actuator of the PP/PVC plastic manual air valve can be selected according to the specifications of the air valve. torque.

Manual Damper is a kind of non-closed butterfly valve, which is widely used in universities, chemical industry, biology, electric power, energy, environmental engineering, etc. During the production process, the medium temperature is less than or equal to 90℃, and the nominal pressure is less than 0.1Mpa. Connect, open and close or adjust the medium, usually installed at the top of the fume hood, PVC suction hood, and at the entrance of the pipeline of the spray tower to be used as the switching direction of the exhaust gas flow of the spray tower
