RV / IRV Series – 2 & 3 vane rotary vane steering gear
The design's dual, submerged pump power packs make installation even easier, as no expansion tank is needed.
Proven service record
The RV series of steering gear is suitable for large and medium sized vessels and is available with 2, 3 and 4 vane options. A dual, submerged pump powerpack simplifies installation as no expansion tank is needed. Modulated flow control gives a soft start and precise control for small rudder movements. The IRV series incorporates a double sealing system, completely separating the actuator into two individual pressure systems. Automatic isolation of the actuator’s dual hydraulic system is a feature to meet IMO single failure criteria for large tankers over 100,000dwt. They can be supplied with steering controls, CANBUS alarm system and rudder angle indicators. The RV / IRV 2 & 3 vane range is from 430 to 3916kNm.
Key features
- Rudder angles 35 - 70°
