Hydraulic Steering System
HTP Type
HTPR Type
Technical details:
Pressure MTC30: 3923 kPa (40 kg/cm2)
(569 lbs/sq.inch). Pressure MTC52-175: 5492 kPa (56 kg/cm2)
(797 lbs/ sq.inch). Connections: G 1/4 female pipe thread.
Total rudder angle: 70° (2 x 35°).
In the case of a dual steering position, in order to change over from one position to another, the installation of non-return valves is required.
The ideal solution will then be: the installation of two steering pumps, with integrated non-return valve. Another solution could be: steering pumps without integrated non-return valve, plus installation of a separate nonreturn valve block. In the case of single station control, installation of a steering pump without integrated non-return valve will suffice in most cases. This set-ups will provide feed back from the rudder to the wheel. Both steering pump models HTP and HTPR may be fitted with the shaft at any angle between horizontal and vertical. Pump types HTPR are provided with a non-return valve, a pressure relief valve, as well as a “continuous air bleeding system”.
