Abstract
A technique that is usable with a well includes providing a sequencing valve to in a first state to communicate a first flow through a first port of the valve and in a second state close fluid communication through the first port. The technique includes communicating a second flow through an orifice of the sequencing valve during the second state of the valve and using a pressure drop across the orifice to bias the sequencing valve to remain in the second state.
