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.

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.
Dual Fuel System
Valve remote control system for LNG-DF consist of cargo valve control system and ballast valve control system.
