弁。 It has a pressure reducing type pressure compensating valve 1 and a flow rate control valve 2 connected downstream thereof. A high pressure groove 5 and a pressure reducing groove 6 adjacent to the high pressure groove 5 are provided around the inner spool 4, and the high pressure groove 5 is connected to the pump port P, and the high pressure groove 5 is connected to the pressure reducing groove 5. The secondary port 9 of the pressure reducing valve 1 is connected to the primary port 8 of the pressure compensating valve 1, and the reducing groove 6 is opened and closed by the movement of the spool 4. The fluid pressure downstream of the variable orifice 10 is connected to the spring chamber 11 of the pressure reducing type pressure compensation valve, and the variable orifice 10 is connected to the pilot chamber 12 of the valve. In a flow control valve with a pressure compensating valve that guides the fluid pressures of the front fluids and makes them face each other, a plurality of oil grooves 21 are provided on the outer periphery of the spool 4 located between the high pressure groove 5 and the pressure reducing groove 6.
A flow control valve with a pressure compensation valve, characterized in that it is provided with a pressure compensation valve.
