PURPOSE: A two-way solenoid valve is provided to overcome the disadvantages of the long transfer distance of an iron core, the higher requirement of manufacturing precision, and a complex structure by employing a variable flow control unit of various structures. CONSTITUTION: A two-way solenoid valve comprises a valve body part(2) which includes upper and lower valve bodies(23,21). The upper valve body, which acts as a valve guide, includes a return spring(238) which is provided between movable and fixed cores(232,239) arranged in a sleeve, an upper valve seat, and a valve seat boss. The upper and lower valve bodies are sealed and fixed together.
