The BFF-S stainless steel float valve requires a pilot sub valve (ball float) that controls the main function of the valve via a 1/2\ BSP female threaded adaptor. When the ball float drops and opens it releases the back pressure the main BFF valve which then opens to refill the tank, when the level rises the ball float lifts and closes to generate back pressure that then closes the main valve and water flow stops.
