PURPOSE: To reduce the space for installation and simplify an assembling operation by joining a pressure control valve to the discharge port of a control valve and making the both valves in an integrated form.
CONSTITUTION: A pressure control valve S is assembled in an integrated form to a control valve V, and its cylindrical casing 19 is screwed to the exhaust port 2 of a body 3, connecting the inside of the casing 19 to an annular groove 12. In the control valve V, a spool port 4 is formed in the body 3, in which a supply port 1 connected to a pump P and the discharge port 2 connected to a tank T are formed, and a spool 5 is slidably provided in the spool port 4. The both ends of the spool 5 are projected into reaction chambers 6, 7, allowing the spool 5 to hold the neutral position by means of the action of springs 8, 9.
