At dredge works we now give you a more affordable option for your regulator valve. We now go back to the original Hoffer valve that was operated by set point operation. This system is a more basic model and shows the true simplicity of the system. The valve will open when a set point is reached and close when below the set point. The system works quite well and leads to the concept of the minimal use of the by pass valve . The valve only opens in critical situations and does not try to regulate flow. You will always know the true reading of your gauges and not a modified reading due to the valve. System reads Vacuum, Discharge PSI, and  Velocity. This is a good option for producers and works quite well.
