A position indicator with Namur mounting is standard
on all HAITIMA pneumatic actuators for mounting
The hardened alloy steel pinion is precision ground
and Nickel plated (over 25um) in order to reduce
friction, provide maximum wear resistance. Full
conformance with the newest standards of ISO5211 &
DIN3337. The dimensions can be customized and as
options, stainless steel and aluminium are also
- Actuator Body
The aluminum extrusion is hard anodized (over 30um)
to protect against wear and corrosion while reducing
piston friction to the absolute minimum. Other
options such as Nickel plating, PTFE and powder
polyester painting are available.
- End Caps
Epoxy coated (over 150um) die cast aluminum end caps
provide maximum resistance against potentially
corrosive elements. Other treatments such as Nickel
plating & PTFE painting are available.
The precisely-balanced and hard anodized treatment (over
30um) die cast aluminum pistons are fitted with
high quality rings and guides. The twin rack and piston design
creates a constant torque output on all
The standard adjustment is
+ 5° in both the open and
closed positions through easily accessible external adjustment
High Performance Springs
The high tensile steel
springs are coated with zinc phosphate for corrosion resistance and
The pre-loaded springs can be safely & rapidly disassembled.
Bearings and Guides
The highly durable compound material provides high trust stability
with minimum friction and long life.
NBR O-rings provide trouble-free operation at standard temperature
ranges. Viton and Silicone O-rings are
available for high or low temperature applications.
