The original Hoffer valve invention was to control cavitation or a plugging slurry line. Today it is many times marketed as a production tool which is misleading. If used incorrectly a bypass valve will reduce or limit production. At Dredge Works we feel the original use is still the best application.

   Today the bypass valve has now become a common tool for dredging.  The valve controls high vacuum, high PSI, low velocity and density limit.  A valve is better than none, and in many cases, can increase production due to controlling the maximum parameters that can be achieved.  Since you are diluting the slurry by adding water, a bypass valve should not be overused.  Trying to pump with the valve in a partial open decreases production. If the valve is open for a prolonged time , water will take the path of least resistance and production will be reduced. Also your basket may begin to plug due to this situation.  Our system has a closing bias programming and when the valve is open too long a warning instructs dredge operator to raise the ladder.  We have over 40 years of dredging experience and 20 yrs of designing and building dredging systems. You will not increase production by continual dilution of slurry. Our regulator is a modern, modulating valve system, which includes the hydraulic system, regulator valve, control CPU and all sensors needed. All of our automation systems have a manual operation option. This assures you will never have to shut down due a sensor cpu failure.
