First, product overview:

　Pneumatic glass lined discharge valves are mainly used for the bottom discharge of reactors, tanks and other containers, connected to the bottom of the tank and other containers by means of the bottom flange of the valve. Glass lined discharge valve according to the needs of the actual situation, the bottom structure design is flat bottom type, the valve body is V type, reasonable structure design, to ensure that there is no residual liquid inside the valve body. The valve body cavity is equipped with erosion resistance, corrosion resistance of the sealing ring, in the opening of the valve moment, can protect the valve body from being washed by the medium, corrosion, and special treatment of the sealing ring, the surface hardness of HRC56-62, with high wear resistance, corrosion resistance function. Widely used in chemical industry, medicine, dyes, pesticides, organic synthesis, petroleum, food manufacturing and national defense industry and other industrial production and scientific research.

Second, product anticorrosion performance:

　　For all kinds of concentrations of inorganic acid, organic acid, organic solvent and weak alkali medium are strong rot resistance. However, it is not applicable to strong alkali, hydrofluoric acid and fluoride ionic medium, and phosphoric acid whose temperature is greater than 180℃ and concentration is greater than 30%.

Third, product features:

1. Good sealing performance. Conical valve enamel core head deep into the feeding pipe mouth, feeding can be the residue, crystal top loose, no accumulation, no leakage.


2. Good flatness. The valve is made of special corrosion resistant porcelain glaze, the surface of the porcelain layer is smooth, non-stick material, not easy to scale.


3, good corrosion resistance. In the vast majority of alkaline and strong acid and other harsh corrosion conditions, can be used for a long time.


4, excellent temperature resistance, suitable for the temperature of 0℃-200℃, safe use temperature of 0℃ -140 ℃.


5, good pressure resistance. The valve can withstand the ultimate negative pressure and positive pressure 0.6Mpa. Under special circumstances, it can withstand positive pressure of 2.5Mpa.


6, good weather resistance. The valve can be used at normal temperature and pressure for a long time.


7. Easy installation and application. The valve is easy to install, easy to operate, high automation bearing.


8. High degree of intelligence. The valve can be operated on site, but also transmitted to the operating room. Monitor valve switch position and opening at any time. With automatic shutdown function to prevent power failure to the valve.


9. Manual integration design. In the emergency state such as power outage and gas stop, you can manually operate the valve.


10. High explosion-proof rating. The valve all parts are designed in accordance with the chemical workshop explosion-proof requirements. 24V safe DC voltage power supply, and equipped with explosion-proof interface.


11, with multifunctional design. The valve can be customized with explosion-proof temperature measuring device, which can accurately monitor the working temperature of the materials inside the reaction kettle.
