A pneumatically actuated valve (44) includes a valve body (46), a pneumatic actuator (48), and a pitot tube (72). The valve body includes a valve disc (52) positioned in a valve housing (50) that defines a flow passage (56) with a flow passage diameter (D). The pneumatic actuator (48) rotates the valve disc (52) in the valve housing (50). The pitot tube (72) is connected to the pneumatic actuator (48) and has a tip (78) extending into the flow passage (56). The tip is spaced apart from the valve housing (50) by at least 1/20 of the flow passage diameter (D). The tip (78) is substantially free of downstream obstructions for a distance equal to at least 1/2 of the flow passage diameter (D) when the valve (44) is in an open position.
