A paint change valve comprises a valve stem (2) formed with a closure member (5) at one end and attached at the opposite end (3) to a flexible diaphragm (13) of paint solvent resistant material which seals the paint chamber (16) from a control air chamber (17). The paint pressure acts on one side of the diaphragm to close the valve while control air pressure acts on the other side of the diaphragm to open the valve. <IMAGE> |
