制御弁。 A cylindrical valve seat held within the valve body, a valve stem movably mounted within the valve seat coaxially with the valve seat, and a valve seat outlet inner diameter located downstream of the valve seat outlet and attached to the outer periphery of the valve stem. The valve seat of the valve stem is provided with a valve seat formed in the shape of a flange having a larger diameter than the valve seat, and the valve seat of the valve stem controls the flow rate of gas passing through the valve seat by engagement between the valve seat and the valve seat. A flow control valve characterized in that a plurality of grooves are carved in the axial direction on the outer periphery upstream of the flow control valve, and the grooves are narrow and extend to the same vicinity with respect to the valve seat.
