This self-actuating check valve responds automatically to changes in pressure and flow within a system. Its slim, face-to-face dimension saves space by allowing the valve to fit in close piping arrangements.

CHEXTER adapts to all flow conditions and closes prior to reverse flow in the system, thereby preventing water hammer. The eccentric mounting and contoured design yield flow coefficients much higher than most check valves, and the only moving part is a disc that opens at very low differential pressure. Choose from a variety of seating options with interchangeable and field-replaceable parts.
