DIRECTION CONTROL VALVE WITH METERING NOTCHES ON THE SPOOL FOR REDUCED FLOW IN THE OPEN END POSITION

摘要

A valve includes a pressure limiting flow spool disposed in a valve body. The spool is movable in a first direction from a first position to a second position and in the first direction from the second position to the third position. The valve includes an inlet and a first outlet. The first position is a closed position preventing flow from the inlet to the first outlet, the second position is a maximum flow position having a maximum flow capacity from the inlet to the first outlet, and the third position is a pilot flow position having a reduced flow capacity from the inlet to the first outlet smaller than the maximum flow capacity.
