Gate valve
On some vessels, additional transducer protection is required. One example is vessels working in arctic conditions. It is important for them to prevent ice from damaging the transducer. A gate valve can then be added to the hull unit installation. By means of a mechanical construction it shuts off the bottom of the installation trunk when the CS90 is not used. The gate valve is manufactured by LK Valves.
The installation trunk normally used for hull unit installation is not used when a gate valve is mounted. The installation trunk is replaced with a transducer dock.
Note
The gate valve is placed at the bottom of the transducer dock. It will then increase the total height of the hull unit installation.
•  The CS90 Hull Unit is designed to lower the transducer 1.0 meter below the ship’s hull. This depth is decreased with the physical height of the gate valve. It is further decreased with the height of the mounting flange.
•  The CS90 allows you to define a middle position for the transducer. When you define the middle position, you must take the total height of the gate valve and the mounting flange into consideration.
The CS94 Hull Unit is designed to lower the transducer 2.1 meter below the ship’s hull. This hull unit is a better choice if a gate valve is used.
Technical information about this unit is not included in this CS90 Installation Manual. Refer to the relevant end-user documentation provided by the manufacturer.
