China Xicheng Environmental Protection Company specializes in the production of PVC plastic manual air damper, suitable for chemical, laboratory, and other ventilation systems with explosion-proof requirements. PVC plastic manual air dampers are composed of plastic dampers and pneumatic actuators. Dimensions Support customization, square or round.
The PVC plastic manual air damper is made of PVC and is resistant to acid and alkali corrosion. The working principle of the PVC plastic manual air valve is the same as that of the 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 PVC plastic manual damper.
PVC plastic manual air valve is suitable for application environments with explosion-proof requirements such as chemical plants and laboratories. It is used in PVC ventilation pipe systems and is connected with PVC air pipes. It is used for exhaust control of corrosive gases, corrosion-resistant, and acid-resistant. Alkali, PVC plastic manual air damper has complete specifications, supporting PVC air pipes, elbows, tee, and variable diameters to form a complete PVC ventilation piping system. The pneumatic actuator of the PVC plastic manual air valve can be selected according to the specifications of the air valve. Torque.
PVC plastic manual air valve is a non-closed butterfly valve, which is widely used in universities, the chemical industry, biology, electric power, energy, environmental engineering, etc. In the production process, the temperature of the medium is ≤90℃ and the nominal pressure is less than 0.1Mpa. Connecting, opening, and closing, or adjusting the medium, is usually installed on the top of the fume hood, PVC suction hood, and at the entrance of the one-use one-standby spray tower pipe, as a switch to the spray tower exhaust gas flow direction.
PVC plastic manual dampers are installed in PVC/PP piping systems. Through manual operation or PLC automatic control technology, the damper can be opened and closed as required. The principle is to install plastic blades in the damper, and the damper is driven to rotate by the damper actuator. , drive the butterfly valve blade to rotate, realize the 90-degree turning angle, achieve the purpose of opening and closing, and have the function of feedback indication. Through the differential pressure detection device, after closing the air valve, the signal is transmitted to the PLC system, so as to control the speed reduction and energy-saving operation of the PVC fan inverter.

PVC plastic manual air damper features
1. No corrosion: PVC pipe dampers can withstand the corrosion of PH value in a wide temperature range, ranging from 1 to 14 in high concentrations of acid and alkali.
2. Wear resistance and no scaling: The inner wall of PVC pipe dampers and fittings is uniform and smooth, with small flow resistance and no scaling.
3. Reduce vibration and noise: PVC pipe damper has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.
4. Anti-freeze cracking: PVC material has excellent elasticity, so that the section of the pipe and pipe fittings can expand together with the frost-heaving liquid without bursting.
5. Anti-condensation, less heat loss: PP material is a poor thermal conductor, which can reduce condensation and reduce heat loss.
6. Simple installation: PVC pipe damper is light in weight, easy to install and operate, and has weldability.
