Claims

[Scope of utility model registration request]

(1) A speed control valve section consisting of a comparison valve and a check valve inserted into a passage formed inside the valve body that communicates the actuator side and the directional control valve side valve port, and this speed control valve section. A control valve characterized in that a pressure reducing valve section connected in parallel is integrally constructed. ′

(2) A valve case having first and second ports and a passageway communicating the first and second ports, a speed control valve section inserted into the passageway, and the speed control valve. a pressure reducing valve section inserted into the passage in parallel with the speed control valve section, and the speed control valve section includes a throttle valve that can be adjusted from the outside of the case, and a check valve that is in series with the throttle valve. Claim 1, wherein the pressure reducing valve part is adjustable from the outside of the valve case and allows fluid to flow in a direction opposite to the check valve of the speed control valve part. control valve. (2) The first port is a directional valve side valve port, and the second port is an actuator side valve port, and the pressure reducing valve, throttle valve, and check valve are all arranged concentrically. The control valve according to claim 2.
