The utility model relates to a hydraulic technology field, concretely relates to a
transition function hydraulic valve, a
transition function hydraulic valve, include: valve body, be provided with pressure oil port, oil return and at least one work oil port on the valve body, valve core, the valve core is assembled in the valve body, and the on-off of sliding control oil port, when the valve core is in the middle position, the work oil port is disconnected with pressure oil port, oil return, the valve core is from the middle position and is moved to the work position that work oil port and pressure oil port are communicated between the first transition position and the second transition position that form in proper order, when the valve core is in the first transition position, pressure oil port and the throttling communication between the work oil port, when the valve core is in the second transition position, pressure oil port and the throttling communication between the work oil port, simultaneously, pressure oil port still and the throttling communication between oil return, solved the
transition function hydraulic valve in the prior art, will
delay work oil port
response time, cause the technical problem of action
lag.
