The original Hoffer valve invention was the start of the widely used principle of dredge “cruise control”.

Originally intended to manage flow disruptions  and pump cavitation. The by pass valve has now become a common tool for dredging.  The valve controls Hi Vacuum ,  Hi Psi and Lo Velocity. A valve is better than none, and in many cases, can increase production due to controlling the maximum parameters that can be ran.  This being said you can’t truly reach maximum production due to the limiting factor of running at a fixed or mostly constant rpm and also by dilution due to adding water.  Using a valve with our velocity control system together is the only way to reach your maximum production. Our regulator is modern and is a modulated valve system. System includes the hyd system, regulator valve, control cpu and all sensors needed.
