Abstract:
An example valve assembly includes a meter-in valve configured to be fluidly coupled to a first source of pressurized fluid and control fluid flow from the first source of pressurized fluid into a first chamber of an actuator; a counterbalance valve including configured to open and control fluid flow from a second chamber of the actuator to a tank in response to a pilot pressure fluid signal received at a pilot port of the counterbalance valve; and a pressure reducing valve configured to be fluidly coupled to a second source of pressurized fluid and to be fluidly coupled to the pilot port of the counterbalance valve, where the pressure reducing valve is configured to receive pressurized fluid from the second source of pressurized fluid and, when actuated, provide the pilot pressure fluid signal to the pilot port of the counterbalance valve.

Claim (Index 1):
A valve assembly comprising:\n a meter-in valve configured to be fluidly coupled to a first source of pressurized fluid and control fluid flow from the first source of pressurized fluid into a first chamber of an actuator; a counterbalance valve comprising: (i) a first port configured to be fluidly coupled to a second chamber of the actuator, (ii) a second port configured to be fluidly coupled to a tank, and (iii) a pilot port, wherein the counterbalance valve is configured to open and control fluid flow from the second chamber to the tank in response to a pilot pressure fluid signal received at the pilot port; a pressure reducing valve configured to be fluidly coupled to a second source of pressurized fluid and to be fluidly coupled to the pilot port of the counterbalance valve, wherein the pressure reducing valve is configured to receive pressurized fluid from the second source of pressurized fluid and, when actuated, provide the pilot pressure fluid signal to the pilot port of the counterbalance valve, wherein the pilot pressure fluid signal has a reduced pressure level compared to pressurized fluid received from the second source of pressurized fluid; and a controller configured to send a first command to the meter-in valve so as to provide fluid to the first chamber of the actuator, while sending a second command to the pressure reducing valve so as to provide the pilot pressure fluid signal to the pilot port of the counterbalance valve, such that actuation of the meter-in valve is decoupled from actuation of the counterbalance valve.
