Abstract
A fluid flow control valve, particularly for use in a gas turbine engine fuel control system has an orifice with a closure member which is urged open by a pressure signal and which is urged shut by a biasing spring. The bias applied by the spring is variable by an input control lever and the response of the spring bias variation to lever movement is itself adjustable.
