Valve Remote Control

Our valve remote control systems (VRCS) enable valves to be operated by a press of the button and have the ability to operate several valves at the same time. This translates into lower operating costs for our customers as with our systems in place, fewer staff are required onboard their vessels. Our systems offer proven technical solutions for any flow control application for the handling and transferring of liquid cargo, LPG/LNG, ballast, bilge and fuel oil on all types of marine vessels and offshore installations. Our wide array of valve remote control systems includes hydraulic , pneumatic, electric and electro-hydraulic options.


 

 

 

Hydraulic Valve Remote Control Systems

NORDIC’s Hydraulic Valve Remote Control Systems (VRCS) offer compact, safe and reliable solutions to any vessel. Our systems enable valves to be operated by a press of the button and have the ability to operate several valves at the same time. This translates into lower operating costs for our customers as with our systems in place, fewer staff are required onboard their vessels.

 

Our systems offer proven technical solutions for any flow control application for the handling and transferring of liquid cargo, LPG/LNG, ballast, bilge and fuel oil on all types of marine vessels and offshore installations.

 

Our standard Hydraulic VRCS consists of:

  • Hydraulic Actuators
  • Hydraulic Power Units and Handpump units
  • Solenoid Valve Cabinets / Intrinsically Safe Deckboxs
  • Control Consoles / Mimic Panels / Control Stations
  • Processing Cabinets
  • Accessories for submerged applications

 

 

 

Pneumatic Valve Remote Control Systems

NORDIC’s Pneumatic Valve Control System offers an environmental friendly and cost efficient solution. Our compact design ensures space requirement are minimised without compromising its reliability.

 

In a decentralised system, Namur mount solenoid valves are mounted on the pneumatic actuators. This configuration does away with the solenoid valve cabinet which further reduce the space required for the system.

 

Our standard Pneumatic VRCS consists of:

  • Rack & Pinion / Scotch Yoke Pneumatic Actuators
  • Solenoid Valve Cabinets / Intrinsically Safe Deckboxs
  • Control Consoles / Mimic Panels / Control Stations
  • Processing Cabinets
  • Namur-mount Solenoid Valves for decentralised system

 

 

 

Electric Valve Remote Control Systems

NORDIC’s Electric Valve Remote Control Systems provide a compact, all-in- one solution for your electrical actuation needs.

 

Our standard Electric VRCS consists of:

  • Electric Actuators
  • Control Consoles / Mimic Panels / Control Stations
  • Processing Cabinets

 

 

 

Electro-Hydraulic Units (EHU)

The NORDIC Electro-Hydraulic Unit (EHU) is an integrated electro-hydraulic valve remote control system used for controlling valves and actuators remotely, developed to be mounted directly on Nordic’s actuators on board vessels and offshore platforms.

The EHU consists of a hydraulic pump driven by an electric motor. When in operation, the oil is siphoned from the tank through the suction to the pump, which then goes through the pilot operated check valve to the actuator port, causing the actuator to open the valves.

When the valve is fully opened, the motor will be stopped by a limit switch. The actuator in this instance will be hydraulically locked in position by the pilot check valve. Emergency operation can be conducted for both double and single acting EHU using the manual override using a portable hand pump connecting to the quick coupling port.

For single acting EHU, during loss of power, the normally open 2/2-way solenoid poppet valve open contact and causes hydraulic pressure to drop. Compressed spring will be released and quickly closes the valve for safety purpose.

Alternatively, NORDIC Electro-Hydraulic actuators can be operated locally through a Local Control Box. The Local Control Box contains two push buttons for “OPEN” and “CLOSE” functions, and a Local/Remote key to choose the mode of control, whether locally or remotely. In addition, Electro-Hydraulic actuators can be interfaced through Fieldbus.
