Poisonous and harmful gases, chlorine gas, liquid chlorine medium choose bellows globe pneumatic valves

in the petroleum, chemical, pharmaceutical, chemical fertilizer, power industry and other fields, chlorine gas because of its superior oxidation performance, often used as oxidant in chemical reaction, also because of its toxic nature be rejected by the people. So on chlorine with pneumatic valves, the user should choose what kind of products, ensure the safety of chlorine gas, liquid chlorine transport does not leak.
as bellows globe pneumatic valve when put through or cut off the pipeline medium excellent sealing performance, it is often used in chlorine gas, liquid chlorine and other toxic medium transport using process ensure the zero leakage. Chlorine gas/liquid chlorine bellows globe for nominal pressure pneumatic valve: PN. ~。 - Mpa/LB ~ LB, working temperature ~ ℃ of petroleum, chemical, pharmaceutical, chemical fertilizer, the power industry such as chlorine gas/liquid chlorine/phosgene/chlorosilane condition of pipeline, cut off or connect pipe medium.
move corrugated pipe cut-off valve for liquid chlorine gas pneumatic valve adopts unique design of bellows seal thus completely eliminate the pneumatic valve stem packing seal leakage problem, meet the most stringent leakage level requirements. (1) cavity of the corrugated pipe is completely isolated role, (2) the packing in the packing box is attachment. Import bellows globe zero leakage characteristics of pneumatic valve to improve the safety of the equipment, save a lot of energy, reduce the maintenance cost, and for the industrial application provides a clean and safe work environment. Ordinary corrugated pipe cut-off pneumatic valve bellows in pneumatic valve body cavity, piping within the medium directly impact the corrugated pipe, corrugated pipe leaking, easily damaged not sealing function. Improved pneumatic valve is raised to the pneumatic valve bonnet bellows, bellows under protection, effectively avoid the scour of the medium and medium impurities to the destruction of the bellows. Connection standard flange, butt welding and socket welding, pressure rating of PN, ANSI, and CLASS. Chlorine gas/liquid chlorine medium pneumatic valve body material selection (low temperature corrosion resistant steel LCB/LF, containing titanium nickel plated stainless steel bellows or hartz alloy C, pneumatic disc LF + PTFE/STL.
import bellows globe pneumatic valve can also be used for alkali, polycrystalline silicon, PVC, propylene oxide, titanium tetrachloride chloride medium technology, and industry in all kinds of high-risk dielectric fluid.
