DC1420 物料角閥                                                                                                      DC1420  Bottom outlet angle valve

DC1420物料角閥一般安裝在容器或者反應釜的底部，對該類型閥門的工作穩定性、可靠性及壽命有較高的要求。其光滑流線型的閥體流道設計，球形單座的閥芯形式，易于介質的流動。廣泛應用于聚合反應、化纖、食品、發酵等行業，對于漿料、高密度流體場合，亦是理想的選擇。在選用該型號閥門時，必須認真考慮介質的物理性質，化學物性，溫度，壓力等因素對閥門的影響，確保閥門能正常工作，避免因此產生安全事故。根據作用形式的不同可分為上展式物料角閥和下展式物料角閥。根據安裝位置的不同可分為45°和60°以及90°三種形式。

The DC1420 material angle valve is generally installed at the bottom of the vessel or reactor, which has high requirements for the stability, reliability and life of the valve. Its smooth and streamlined valve body runner design, spherical single-seat spool form, easy to flow media. Widely used in polymerization, chemical fiber, food, fermentation and other industries, it is also an ideal choice for slurry and high density fluids. When selecting this type of valve, we must carefully consider the physical properties of the medium, chemical properties, temperature, pressure and other factors on the valve to ensure that the valve can work properly, to avoid the occurrence of safety accidents. According to the different forms of action, it can be divided into an upper material angle valve and a lower material angle valve. It can be divided into three types according to the installation position: 45° and 60° and 90°.
