Abstract
A pneumatically actuated valve includes a valve body, a pneumatic actuator, and a pitot tube. The valve body includes a valve disc positioned in a valve housing that defines a flow passage with a flow passage diameter. The pneumatic actuator rotates the valve disc in the valve housing. The pitot tube is connected to the pneumatic actuator and has a tip extending into the flow passage. The tip is spaced apart from the valve housing by at least 1/20 of the flow passage diameter. The tip is substantially free of downstream obstructions for a distance equal to at least ½ of the flow passage diameter when the valve is in an open position.
