For larger boats, VETUS hydraulic power steering is a most comfortable and extremely safe steering system. The effort required at the helm is only about 10% of a non-powered steering system. In other words: the boat can be steered literally with one finger. Because of this, the steering wheel diameter can be considerably smaller than normal; a wheel diameter of just Ø 360 mm will usually suffice.
VETUS hydraulic power steering is extremely safe. Should there be a power assistance failure, then the steering system will still operate unassisted, only with somewhat greater effort. The pump unit is in fact a rotating proportional valve. By turning the wheel, this control valve opens and directs oil under pressure to the steering cylinder connected to the rudder. The volume of hydraulic fluid that is circulated, is dependent on the model of steering pump, the number of wheel revolutions and the speed at which the wheel is turned. The VETUS steering pump has a closed mid position, ensuring that there will be no oil flow as long as the wheel remains untouched. To connect one or more VETUS steering pumps and/or an automatic pilot to a VETUS hydraulic system, a control unit model HT1019 must be used.
The external flange of the steering pump is made of seawater resistant aluminium, hand polished and anodised. The steering wheel shaft is made of stainless steel, type I-4462, Ø 19 mm, taper 1:12.
The VETUS hydraulic power steering has been developed for application within the “VETUS Power Hydraulics” programme, which is based on the “constant pressure” (load sensing) principle. If your boat is equipped with a hydraulic system which does not operate on this principle, VETUS will gladly advise on how to adapt your system, in order to enable installation of this type of steering.
