With pressure rating up to 19 bargs, the DOXI ball check valves sight glass are very robust, having integrated borosilicate windows each side of the ball check assembly makes it very easy to see if there is flow through the valve. No wetted metal parts are used. The valves are immune to most aggressive chemicals and are used in place of expensive exotic alloys.
