Description

FR12-33X is a screw-in, an adjustable, pressure compensated, type with reverse flowcheck flow control valve

Operation

The regulated flow increases from closed to fully open with counter-clockwise adjustment rotation. The valve will maintain the set flow regardless of pressure variations on the regulated or bypass port.
