Aluminums Shell Dual Action and Single Action Type (Spring Return) 4 Piston Pneumatic Actuators

THERE ARE BIG ADVANTAGES TO THINKING SMALL

SonicTorque 4*4 utilizes carbon steel pistons that allow for higher cycles because of their greater strength.

Viton seals in the piston drive shaft also lead to higher cycles. Inside surface finish (Ra 0.4-0.6um) to minimize

friction and to maximize the life of the actuator.

Standard applications for temperature ranges from

BUNA    -4 Fto 176 f   -20 c to 80 c

Also available Viton   -4 F to 250 F   -20 c to 120 c

EPDM    -40 Fto 176 F   -40 cto 80 c

Piston bearing made of material with low friction coefficient to avoid metal to metal contact. Easily replaceable for

maintenance.

Double lower drilling for valve mounting, and centering, according to ISO 5211/DIN 3337 standards.

Independent   bi-directional   travel   stop  adjustment   -5ensuring  precise   positioning   in   all flow   control   services,

adjustable between 85-95rotation.

Direct mounted solenoid connections according to NAMUR standards.Lower female shaft key, according to ISO

5211/DIN 3337 standards, for assembly on valves with star or square shaft.

The lubrication carried out by the manufacturer qualifies for a minimum of 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,  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.
