Abstract

PURPOSE:To protect a valve plug from thermal damage, by providing a charge port provided in a valve body and a valve plug which opens or closes a connecting part of piping, a single valve seat and a flow duct. CONSTITUTION:A valve body 22 molded in a body by forging possesses a connecting part 22a of a connecting piping 23 and a connecting part 22b of a coolant pipe 35, and a flow duct 24 connecting the connecting parts 22a and 22b is formed inside the valve body 22. Only a front seat 25 is formed in the midway of the flow duct 24 as a valve seat. Then, a valve plug 26 is screwed into the valve body 22 so as to allow its free advance or retreat movement, and the flow duct 24 is opened or closed as the tip of the valve plug 26 is touched or detached to the front seat 25.
