Description
The PVC plastic manual air valve is made of PVC material, which 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. 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. Alkali and PVC plastic manual air valves have complete specifications, and are equipped with PVC air ducts, elbows, tees, and reducers to form a complete PVC ventilation duct 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 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
