This company introduces a patented Disposable Material Path™ (DMP) valve that contains a disposable feed screw for easy maintenance, and more accurate and reliable dispensing. With a feed screw made of Delrin, the valve is designed for use with two-compound and abrasive materials. The DMP valve has a hinged doorway so that the disposable auger can be removed, disposed of and replaced within seconds while the line is still in operation.
