产品简介/Porduct Introduction
STDE(B)系列热力膨胀阀是采用技术标准专门设计，适用于空气调节系统、热泵、汽车空调、冷水机组、冷藏箱和传统的制冷系统。
直通阀，与制冷系统的连接方式为钎焊形式。
STDE为标准单向流口形式
STDEB为平衡流口形式，专门为8-19TR而开发的产品，防止冷凝压力和蒸发负荷的变化而导致静态过热度的变化。
可提供K系列、AC系列和N系列三个不同应用温度范围的系列产品。
适用于R22，R134a和R407C三种制冷剂。
STDE(B) Series thermal expansion valve adopts the top class technic,is used for air-conditioner system,heat pump,auto air-conditioner,chiller,reefer and traditional refrigeration system.
Throughway Valve,Solder connection
STDE: One-way outfall type
STDEB: Equalization outfall type,developed for 8-19TR to prevent the change of static superheat caused by the change of condensing pressure and evaporating load.
Have K,AC ;and N series for different temperature range
Suited for ;R22,R134a and R407C
