A method can include checking states of valves of equipment with respect to a workflow specification according to a checking order defined by assigned numbers; responsive to the checking of the states of the valves, identifying individual valves that are not in a corresponding state as indicated by the workflow specification; and generating a sequence for changing the state of each of the individual valves that is not in its corresponding state to its corresponding state.

Hydraulic fracturing valve system

A technique facilitates greasing of valves on a well tree, e.g. a frac tree, according to a simple process which enables selected, individual valves to be greased when desired. In some applications, the greasing process may be automated and controlled via a greasing control system. According to an embodiment, a greasing system is connected with grease ports at a plurality of actuatable valves located in a well tree. The greasing system has a plurality of grease valves which may be associated with each of the actuatable valves, e.g. with each of the grease ports. A pump is used to pump grease to the grease valves and the grease valves are selectively actuated to open positions to provide controlled greasing of desired actuatable valves so as to remove debris from and to lubricate selected actuatable valves.
