Features 

 VAHN-TECH Compact Pneumatic Actuator 4x4 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.

 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 +/- 5° ensuring precise positioning in all flow control services, adjustable between 85°- 95° rotation.

 Direct mounted solenoid connections according to NAMUR standards.  Lower female shaft key, according to ISO 5211/DIN 3337 standards, for assembly on with star or square shaft.

 Air supply: can be dry or lubricated filtered  compressed air.

 High quality lubricants allow for a minimum of 1,000,000 operations.

 Epoxy powder coating is performed on clean and sandblasted components.

 Visual position indicator the 4x4 actuators are supplied as standard.

 The indicator designed to remain on the actuator for continuous indication when limit switch is being used.
