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

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

Extremly compact

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 6550 kN.

Key features

  • Simplified maintenance: 4-piece split bearings and seals on base and cover
  • Integrated storage tank and rudder carrier
  • Full overhaul possible without removing the rudder stock connection for steering gear sizes of RV2600-4 and over
