| description | Example methods and apparatus independently control the seating force in a rotary valve. An example apparatus includes a rotary valve having a flow control member and a dual-acting actuator operatively coupled to the rotary valve. The actuator has first and second ports to receive a pressurized control fluid to change a position of the actuator. The example apparatus further includes a valve controller operatively coupled to the actuator to control the pressurized control fluid in response to a position of the rotary valve. The example apparatus further includes a pressure limiter operatively coupled to the valve controller and fluidly coupled to the first port of the actuator. The pressure limiter is to reduce a pressure of the pressurized fluid provided to the first port of the actuator to reduce a seating force of the flow control member when the rotary valve is in a closed position. |
