Valve Remote Control System
Valve Remote Control system manufactured by HANLA IMS ard designed according to shipyard specification,client’s requirements and rule requirement of classification society. Our system division in HANLA IMS make an effort to supply the best valve remote control system at a resonable price.
Valve Remote Control System
COMPONENT
Hydraulic Actuator
HANLA IMS hydraulic actuators type HLT-series are especially designed for the operation of quarter turn valves such as butterfly valve, plug valve and ball valves. HLT-Series hydraulic actuators are available in a range of up to 12,800 N.m at maximum working pressure (16MPa - 160 bar).
HLT-Series hydraulic actuators can be operated by stationary hand pump, portable hand pump or manual hydraulic transmitter via quick connectors or fitted pipes.
Electro Hydraulic Actuator
Electro-hydraulic actuator (EHLT-Series) consists of hydtaulic actuator for operating valves, limit weitch box for receiving single feedback, and micro power unit for supplying oil pressure.
Micro power unit consists of electric motor with junction box, oil tank, and main block.
Main block consists of relief valve and pilot check valve. Hydraulic pupm connects with main block at the inside of oil tank.
Normal and ex-proof type are available for electric motor.
It is made of aluminum body in addition to main block.
IP68 of Electro-hydraulic actuator is available for double acting type.
Local Control Cabinet
Hydraulic Power Unit
Hydraulic power unit is designed to simple arrangement, easy control and easy maintenance.
Control box of hydraulic power unit can control the hydraulic pumps (Main/Stand-by) and pump selection and monitor the abnormal alarm as like pressure, level and temperature.
In order to keep the adequate capacity of the accumulator, the hydraulic power delivers the higher pressure than the designed working pressure of VRC system. But the working pressure of VRC system can be limited at the required working pressure by the faction of the pressure reducing valve.
Features
  • Simple design & arrangement
  • Easy control & operation
  • Easy Maintenance
  • Constant hydraulic pressure
Components
  • Hydraulic pump
  • Electric motor
  • Accumulator
  • Pressure relif valve
  • Pressure switch for control with pressure gauge
  • Pressure switch for alarm with pressure gauge & transmitter
  • Pressure reducing valve

Solenoid Valve Cabinet
Solenoid valve cabinet is divided into the hydraulic part and the electric part.
The hydraulic part consists of solenoid valves, flow control valves, manifold blocks, pressure filter and feed back components etc.
The electric part arranges to connect for electric wiring of valve control and feed back signal.
Solenoid valve cabinet controls in accordance with the function of each valve and it is an equipment to process its signal. Through this equipment, it sends the valve position signal to control console or computer and receives the valve position signal, and controls each valve.

LNG CARRIER
COMPONENT
Hydraulic Power Unit
The hydraulic power unit for LNG Carrier consists of two main hydraulic pumps/motors, one hydraulic topping up pump/motor, filters, gauges, electric & hydraulic components, control panels, and so on.
There are two main pumps : one is for mormal operation; another one is for back up operation.
When the standard pressure level is under abnormal condition, the standby pump automatically runs in order to maintain the normal pressure level.
The hydraulic topping up pump is designed to preserve the whole system pressure level when no valve is under operation.
Normally, the hydraulic power units of LNG uses 'piston type pumps' & 'self-regulating type pumps' which keep the hydraulic pressure the standard condition. It supplies the constant pressure in the circuit when the pump runs.
Components
  • Electric motor/Hydraulic pump
  • Filters
  • Pressure switch & Transmitter
  • Level switch & Level indicator
  • Pressure relief valve
  • Temperature switch
  • Accumulator
  • Fitting & Valve, Gauge part
  • Control panel for H.P.U
Solenoid Valve Cabinet
'Solenoid valve deck box for Emergency Shut Down (ESD) system' or 'Solenoid valve deck box' is installed in the passage way or the pump/ machinery room of the hazardous area for LNG carrier. It is constructed to operate the valve and to process the signal.
For the ESD system of valve operation, the ESD valves can be controlled the same as the other valves under the normal operating condition. When ESD solenoid valve is energized, it makes the oil way closed from ESD solenoid valve to closing chamber of the corresponding actuators. When the ESD solenoid valve under ESD condition, however, is dis-energized, it makes the oil way opened from ESD solenoid valve to closing chamber of the corresponding actuator.
Consequently, ESD valves are automatically shut down at ESD condition. The hydraulic power for closing ESD valves at ESD condition is supplied from the hydraulic accumulators. Normally, the capacity of accumulators has the enough power in order to allow the corresponding ESD valves work 2 strokes.
Components
  • Steel cabinet(IP56 grade)
  • Intrinsically safety solenoid valve(Ex ia Type)
  • Manifold block
  • Pressure filter unit
  • Stop valve
  • Flow control valve
  • ESD block with electric/hydraulic components
  • Accumulators
