Type of Actuators:
- 3800D: Double acting
- 3800S: Spring return acting (Air to clock-wise or
counter clock-wise).
Scope of Design:
- Maximum output torque: 3.6 to 3539 Kgf-m
- Cylinder bore: 50 to 300 mm
Canted Scotch Yoke Cylinder Mechanism
Fig.1 shows the comparison between the output
torque curves of a canted, as a constant torque
actuator. (i.e. Rack and pinion type)
These graphs demonstrate that, being the same
the arm length and the cylinder diameter, the
canted scotch-yoke actuator have the most suitable
mechanism, to operate quarter turn valves, from
technical to economical reasons.
Rack & Pinion Cylinder Mechanism
The hardened alloy steel pinion is precision ground
and Nickel plated (over 15 micron) in order to reduce
friction, provide maximum wear resistance. Full
conformance with the newest standards of ISO 5211
& DIN 3337.
The dimensions can be customized and as an option,
stainless steel and aluminum alloy are also available.
Working conditions:
- Maximum working pressure: 8 Kg f/cm2G
- Temperature:
- Standard: -20°C ~ +80°C
- Low: -40°C ~ +60°C
- High: 0°C ~ +150°C
