STDE(B)Series Thermal Expansion Valve
Product Introduction
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 out fall 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
