They are strong and complete of non-return valve, the body has a tank function.
Hydraulic transmitters with this cubic capacity are usually used for emergency
manoeuvres on big systems or as main manual manoeuvre on vessels which have the necessity of using a steering wheel.
These transmitters are also used for small/medium vessels which require a
manoeuvre with the minimum turns of the wheel.
We recommend a 600/900mm as the minimum diameter of the wheel.
