產(chǎn)品簡介/Porduct Introduction
STDE(B)系列熱力膨脹閥是采用技術(shù)標準專門設(shè)計,適用于空氣調(diào)節(jié)系統(tǒng)、熱泵、汽車空調(diào)、冷水機組、冷藏箱和傳統(tǒng)的制冷系統(tǒng)。
直通閥,與制冷系統(tǒng)的連接方式為釬焊形式。
STDE為標準單向流口形式
STDEB為平衡流口形式,專門為8-19TR而開發(fā)的產(chǎn)品,防止冷凝壓力和蒸發(fā)負荷的變化而導(dǎo)致靜態(tài)過熱度的變化。
可提供K系列、AC系列和N系列三個不同應(yīng)用溫度范圍的系列產(chǎn)品。
適用于R22,R134a和R407C三種制冷劑。
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
