Abstract

PURPOSE:To prevent the cavitation occurring at the downstream of a valve body, by providing a through-hole to be closed by a valve box side seat under the full-close state at the circumference of the valve body facing against the flow path formed between the valve body and the valve box side seat. CONSTITUTION:A through-hole 13 having small diameter is formed while having the different phase in the circumferential direction such that it is choked by a valve body 7A and a seat section 5A. The delivery direction under the open state of said through-hole 13, is inclined toward the center of the flow at the immediately downstream of the flow path formed between the valve body 7 and the valve box side seat 5 under slight open state, then the high speed fluid is supplied toward the cavitation area produced at the immediately downstream of the valve body 7 and the valve box side seat 5 due to the high speed flow under the slight open state thus to apply the dynamic pressure on said cavitation area.
