Deck Control Unit
Deck Control Unit is a marine deck-mounted control device designed for remote operation and monitoring of valves and cargo handling equipment on ships.
The unit provides centralized control of marine valves installed in cargo tanks, ballast systems, fuel systems, and other ship piping systems, allowing operators to safely manage equipment from the deck area.
Deck Control Unit is commonly used in:
Oil tanker cargo systems
Tank deck valve control systems
Ballast systems
Fuel oil systems
Marine hydraulic control systems
Remote valve operating systems
Compared with traditional manual valve operation, the Deck Control Unit improves operational safety by allowing crew members to control valves without directly accessing hazardous or difficult-to-reach locations.
Overview
Working Principle of Deck Control Unit
Deck Control Unit transfers operator commands from the deck control position to remote valves or marine equipment.
Depending on the design, the control unit can operate through:
Mechanical transmission
Hydraulic control system
Cable linkage system
Operating Process:
Operator operates the control handle or handwheel.
The control mechanism transfers the operating force.
The connected valve actuator receives the signal.
The remote valve opens or closes.
The indicator displays the operating status.
