ABSTRACT:
Flow regulator valves that adjust to various fluid flow line pressure variations to stabilize flow to designed regulated flow rates in various flow line sizes and with fluid pressure build up in the line encountered such as with water hammer are combined with through flow relief valving to diffuse excessive line pressures. This includes the addition of a relief valve, of any of several configurations, to a flow regulating valve, in several configurations with the relief valve opening to relieve higher than flow regulating valve design working pressures.
