Parker Conflow’s Code 1431 is an inline check valve, which permits movement of flow media in one direction only in water dust suppression systems on mining cutting machines to keep the pipelines "charged" with water. It helps to prevent backflow of fluid media and operates with air, water and oil.

A light spring is fitted to assist with closure at low pressure differentials across the valve. This in-line valve fits neatly into a pipeline with minimum obstruction. It may be used horizontally or vertically.

Code 1431 is available in 3/8", 1/2", 3/4" and 1" sizes and with maximum working pressure of 275 bar.
