VRG offers the best in class, high capacity rotary control valves for midstream and transmission applications. The control valves flow large volumes with low differentials while allowing for exceptional noise attenuation and turndown for high differential and low flow applications. This allows you to plan for a wide set of flowing conditions all within one valve. VRG combines high quality control valves with industry-leading emissions-reducing or emissions-eliminating controls that ensure your facilities and pipelines are environmentally friendly while operating efficiently every single day. All control valves can also easily operate with Fisher DVC6200 positioners if preferred. Competitive pricing combined with ValveSystems's stocking program means that you can get what you need, when you need it, and the Chicago based factory means that valve packages are assembled and tested in the USA.
