DA Rate Controls
ITT DA series rate controls are suited to heavy load applications. These rate controls that are used in pressure or compression jobs, like printing, come with multiple designs. On pressing the rate control, the compression check ball springs into action. When the piston head moves, the oil is forced out of the orifice holes located in the shock tube. Thus the required damping force is attained.
In this process, a part of the oil goes through the check valve and fills up the shock tube rod end. The oil left by the piston rod decreases the foam collect.
