The spool valve chamber is normally biased to move in the direction of closing the flow path between the import and out ports, and depending on the sliding position in the direction of resisting the biasing force,
A control spool that changes the flow path area between these two ports, and an operation spool that can be moved toward and away from this control spool and that can be pressed and displaced by manual operation from outside the valve body are inserted, and this control spool and Between the operation spool and the control spool, there is an on-off valve that normally communicates the outport with the atmosphere, but after the operation spool engages with the control spool, it cuts off the communication of the outport with the atmosphere while the control spool moves together. A manual valve having a flow rate control mechanism, characterized in that it is provided with a flow rate control mechanism. (2) In paragraph 1 of the claims for utility model registration,
The on-off valve between the control spool and the operating spool is a manual valve that has a flow rate control mechanism that reduces the flow path area between both ports as the operating spool approaches the control spool.
