Abstract: A pinch sleeve valve having controllable opening positions regardless of internal sleeve pressure is disclosed. In the past it has not been possible to use a pinch sleeve valve as a control valve because a variation in pressure within the sleeve has affected the opening of the sleeve. The present valve comprises a flexible sleeve with a passageway therethrough, the sleeve having variable positions from a round cross section when fully open, to a collapsed cross section when closed. A rigid pressure sealed housing contains the sleeve and a sensing probe is connected to the sleeve which senses whether the sleeve is fully open, partially open or closed. A valve positioner is connected to the sensing probe and has a control system to set opening positions of the valve regardless of variations in the internal sleeve pressure, the valve positioner controls supply fluid to the housing at a pressure higher than the internal sleeve pressure and sufficiently high to close the sleeve to the desired opening position.
