HABONIM ACTUATORS
CompAct Actuator Features
Pinion
The pinion has a double-square female drive on its bottom plane that complies with
the ISO 5211 standard. The top plane has the NAMUR slot for attachment to switches or
positioners. There is a machined flat below the NAMUR interface to enable manual
operation of the actuator with a wrench.
Indicator & Puck
A highly visible indicator with flow direction arrows is snapped on to the pinion, to provide
easy identification of the valve position. These indicator arrows allow true positioning of any
type of valve entry and direction. The modular design makes it easy to change the indicator
to match various flow patterns.
Safety Features
The CompAct’s built-in safety features ensure secure and safe operation. Assembly and
dismantling of the actuator are simple tasks. Long cover-bolts for spring return actuators
relieve the spring load before they disengage from their threads. Before the pistons can
be removed, the stop screw must be released and the pinion removed thus ensuring that
any trapped and potentially hazardous pressure in the body will escape.
Limit Stop
The pinion and stop rotation can be adjusted by four large-diameter, diametrically-opposed
adjustable set-screws that are threaded into the actuator body. Each opposing pair of screws
exerts simultaneous and equal force on opposite sides of the stop when the rotation limit is
reached, thus preventing the generation of off-center forces.
The stop screws allow for +/-5° rotation adjustment in both directions of travel. Larger span
can be achieved with a longer set of stop screws. This feature is built into the actuator stop
mechanism and eliminates the need for additional plates and screws. The stop material is
stainless steel for better wear and corrosion resistance.
