Classification: F15B,Y10T

Abstract:
A meter-out flow control valve characterized in that it comprises:a first valve for establishing and blocking fluid communication between a first actuator port 73-1 and a tank port 74, the first valve being adapted to be held in its fluid blocking position by a spring 71 and to move to take its fluid communication position in response to an external signal;a second valve for establishing and blocking fluid communication between a second actuator port 73-2 and the tank port 74, the second valve being adapted to be held in its fluid blocking position by a spring 71 and to move to take its fluid communication position in response to an external signal;a first regenerative switching valve 101 disposed coaxially with said first valve for establishing and blocking fluid communication between the first actuator port 73-1 and a first regenerative port 100, the first regenerative switching valve 101 being adapted to be normally held in its fluid blocking position and to move to take its fluid communication position in response to an external signal; anda second regenerative switching valve 101 disposed coaxially with said second valve for establishing and blocking fluid communication between the second actuator port 73-2 and a second regenerative port 107, the second regenerative switching valve 101 being adapted to be normally held in its fluid blocking position and to move to take its fluid communication position in response to an external signal.
