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.
In addition, HLT-Series hydraulic
actuators are applied to any place, even submerged, dry space, on deck and in hazardous
area. HLT-Series hydraulic actuators provide constant output torque over the complete
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
