Abstract
PURPOSE:To enable priority operation of a high-load actuator by connecting metering valves to which pilot pressure of each actuator is conducted in such a manner as to compensate each other to passages of a low-load actuator. CONSTITUTION:Metering valves M1, M2 are connected to passages 15, 16 of a low-load actuator S, whereby pilot pressure of the low-load actuator S is conducted to pilor chambers 31 of the metering valve M1, M2, and pilot pressure of a high-load actuator is conducted to pilot chambers 33. Thus, the travel of main poppets 25 of the metering valves M, M is controlled to determine the opening thereof, so that the high-load actuator can be used for a poppet-type valve. Accordingly, while the high-load actuator being operated with priority, the circuit concerned can be kept leakless.
