A fluid spraying system having a spray gun capable of alternatively selecting a low pressure aerated cleaning or high pressure non-aerated rinsing mode. The system further has an improved interchangeable and disposable fluid cartridge with a combination metering and check valve. The cartridge is sealingly engagable with the gun by use of a bellows fitment. The system utilizes the principle of increased or decreased flow volume to alternatively draw fluid from the cartridge or bypass the cartridge.
