Features

Rack & pinion design.
The standard actuator configuration has hard anodized aluminum body and epoxy coated end caps. External protection; resistance to corrosion of 500 hours in a salty atmosphere, according to ASTM B 117-73.
Inside surface finish (Ra 0.4-0.6 um) to minimize friction and to maximize the life of the actuator.
Standard applications for temperature ranges from -4°F to +180°F.
Special options for extreme temperatures (upon request). Low Temperature Actuator -40°F to 80°F, High Temperature Actuator +5°F to 300°F.
Piston bearing made of material with low friction coefficient to avoid metal to metal contact, easily replaceable tor maintenance.
Double lower drilling, for valve mounting, and centering, according to ISO 5211/DIN 3337 standards.
The indicator is designed to remain on the actuator for continuous indication when limit switch is being used. (Not availabie in SPN 032.)
Independent bi-directional travel stop adjustment +/- 5° ensuring precise positioning in oil flow control services. (Not available in SPN 032.)
Direct mounted solenoid connections according to NAMUR standards.
Same body and end caps for double acting and spring return.
Air supply: can be dry or lubricated filtered compressed air; pressure: min. 40 PSI- 145 PSI.
The lubrication carried out by the manufacturer qualifies minimum 1,000,000 operations.
Epoxy-coating is a deposit of powders on clean and sandblasted pieces. The chemical process is easily kept under control and after coating, the pieces must be subjected to heat treatment. Epoxy painting of actuators is advised where environment is strongly aggressive. With a normal thickness of 200/250 microns of epoxy coating, resistance to salty fog exceeds 1,000 hours. With the exception of certain solvents, epoxy coating resists acids and alkali, and also has a good resistance to UV rays. In order to retain its properties, the coating must not be scratched.
Multi-function position indicator with NAMUR slot to allow visual position indicator.
