steering-gear-4-vane-1020x521.jpg

Extremly compact. The compact 4 vane steering gear is ideal for medium to large vessels and satisfies all statutory requirements for tankers over 100,000 dwt.

This is a range of extremely compact rotary vane steering gear, which is suitable for medium to large vessels including tankers over 100,000 dwt. The 4-vane steering gear is a further development of the well proven range of steering gear with two and three vanes. The key advantages of this design are its compact size because of the four vanes and its light weight as well. The 4-vane steering gear is available as the standard RV model as well as the IRV model, which satisfies all statutory requirements for tankers over 100,000 dwt. This range also incorporates the proven and unique modulated flow control valve. The RV/IRV 4 vane range is from 845 to 6550kN.
