A miniature metering valve is offered with stops and locking mechanism. It is based upon the “MIL-MV-XX” metering valves. The addition of mechanical stops allows users to positively position the sleeve in either the full on or full off position. Users can also reliably position the flow at any point between the two stops by using the engraved scale. A set screw locking mechanism allows the user to lock the sleeve in position once the desired flow rate has been achieved.
