摘要：
A valve device includes a valve body, a drain chamber wall configured to define a drain chamber, a drain port formed in the drain chamber wall facing the valving element, and a drain passage configured to guide drain fluid from another valve device to the drain chamber, wherein at least one of the drain chamber wall and the valving element includes a communicating passage configured to allow the drain port to communicate with the drain chamber when the movement of the valving element is restricted by the drain chamber wall.
