Incorporated in 1998, Nordic Flow

Control started out as a service agent. Through vision and determ

ination, we have forged ahead to becom

e a global m

anufacturer and system integration solutions provider for M

arine, O

il and Gas control system

s, with a sales and support netw

ork that spans Asia and Europe.

To stay ahead of the competition, w

e are constantly raising the bar in quality and technological creativity. N

ordic Flow Control’s Integrated Control and

Managem

ent Systems, w

ill meet any vessel autom

ation needs. From

production to installation, our professional and experienced engineers will

be there every step of the process to ensure customers get the m

ost reliable, user-friendly and technologically advanced control system

s that perform

above their expectations

Backed by international accreditations from various m

arine classification bodies, including ISO

9001:2000 by ABS, Nordic Flow

Control’s one-stop integrated solution has been installed in hundreds of vessels and drilling rigs across the globe. M

ade from the toughest m

aterials and able to withstand

the most dem

anding of marine and offshore situations, our grow

ing reference list bears testam

ent to the reliability of our systems.

Nordic Flow Control Valve Remote Control Systems 1

HYDRAULIC VALVE REMOTE CONTROL SYSTEM

OVERVIEW

Nordic Flow Control’s compact design for our Hydraulic Valve Remote Control Systems does not compromise on power. Our systems operate at a higher torque level even with our smaller actuators. Submerged applications are available, and maintenance is possible even during operation. By having a hand pump in a deck box with solenoid valves, manual operations are now possible.

Our Hydraulic Valve Remote Control Systems are tried and tested in the harshest conditions. The system consists of the hydraulic actuator, a power unit, solenoid valve cabinet, and the control station with operating system.

Our actuators and control systems are able to match and operate valves with no limitations.

ontrol’s actuators are manufactured using sophisticated m

achinery in our own production plant. They

convert hydraulic energy directly into a mechanical rotating m

ovement by using the rack and pinion principle, elim

i-nating cost from

intensive servicing, maintenance and the sensitivity of transm

ission elements.

Our actuators are created for durability, perform

ance and cost effectiveness. Our new

NRA

series actuators are now

more com

pact and provide higher torque at even smaller sizes. They have a longer life span, w

ith higher

Polymer bearings for sm

aller actuators and ball bearings for bigger actuators are used to reduce friction between the

parts. Mounting is according to ISO

5211 standards, but can be customised to m

eet other requirements.

With no need for valves to be dism

ounted, maintenance w

ork during normal operations is possible, cutting dow

n-tim

e needed for repairs. A set of repair kit w

ill be provided for every actuator supplied.

The NO

RDIC Electro-H

ydraulic Unit (EH

U) is an integrated electro-hydraulic valve rem

ote control system used

for controlling valves and actuators remotely, developed to be m

ounted directly on Nordic’s actuators on-board

vessels and offshore platforms.

The EHU

consists of a hydraulic pump driven by an electric m

otor. When in operation, the oil is siphoned from

the tank through the suction to the pum

p, 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 m

otor will be stopped by a lim

it switch. The actuator in this instance w

ill be hydraulically locked in position by the pilot check valve. Em

ergency operation can be conducted for both double and single acting EH

U using the m

anual override using a portable hand pump connecting to the quick coupling

port.

For single acting EHU, during loss of pow

er, the normally open 2/2-w

ay solenoid poppet valve open contact and causes hydraulic pressure to drop. Com

pressed spring will be released and quickly closes the valve for safety

purpose.

Alternatively, NO

RDIC Electro-H

ydraulic actuators can be operated locally through a Local Control Box. The Local Control Box contains tw

o push buttons for “OPEN

” and “CLOSE” functions, and a Local/Rem

ote key to choose

the mode of control, w

hether locally or remotely. In addition,

Electro-Hydraulic actuators can be interfaced through Fieldbus.
