In the disclosed pressure operated valve, a sleeve valve controlling flow between outside and inside the valve is releasably connected in a housing when the sleeve valve is in open position. Pressure on a ball sealingly engaging the sleeve valve operates the sleeve valve from open to latched closed to disconnect positions and expends the sleeve valve from the housing.
