Haitima – HTD – Double Acting


Operation and Construction
Haitima actuators are delivered as double acting (DA) as well as single acting (SR) types.
The return springs on SR type are mounted inside the actuator, and the overall size is equal for both types.
The mounting between valve and actuator is acc. to ISO 5211, and it is Namur connection for solenoid
valves / limit switch boxes.

Range of applications
The actuator is designed for operating of quarter
turn valves i.e ball and butterfly valves.
