HYAB 氣動罐底閥是是一種特殊的切斷閥，主要應用于各種存貯容器的釜底，其光滑流線型的閥體流道設計，球形單座的閥芯型式，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。選用該系列閥門時，必須考慮貯存容器內介質的溫度、壓力、粘附性、腐蝕性等條件，為最大限度滿足不同工況條件，除了樣本提供的標準產品，我們還可根據用戶的特殊要求提供非標設計產品。
HY系列罐底調節閥有兩種結構形式，HYA為上展式，HYB為下展式�？膳�HA薄膜式執行機構和VA、VP汽缸式執行機構。
調節閥的泄漏量符合GB/T4213－2008標準。
Discharge Valve
HYAB Discharge Valve is one of the special on-off valve that is used at the bottom of the stack container. Streamline flow passage and single seated type plug allow the convenient fluid flowing. It is applicable to polymerization, chemical fiber, foodstuff industries as well as fermentation .etc.. We can use it in slurry e high density liquid services. It can must consider fluid temperature, pressure, viscosity and corrosivity when we choose this series product. For all kind of services, we can design the unstanderdized products besides the types in guide book.
This series is divided into two types. HYA Outreaching type and HYB Lift-down type. It can be equipped with HA or VA/VP pneumatic cylinder actuator.
The leakage complies with the GB/T4213-2008 standards.
