Through research,development and design,VAT series pneumatic actuators incorporate the latest mechnical technology,material and innovative ideas.The product proudly boasts the following features:

1) Full conformance to the latest specifcation:ISO5211 DIN3337 VD/VDE3845 and NAMUR.

2) The extruding high intensity aluminum body possess a honed internal surface coated with hone anode oxygenation for long life,low coefficient of friction and swift performance.

3) Excellent,compact and modernized construction along with multi-specifications make the selection both economic and beneficial

4) All acting surfaces adopt high quality bearings,resulting in low friction,high cycle life and on noise.

5) The two independent external travel stop adjustment bolts can easily and precisely adjust ±5 at both open and close directions.

6) Same outline actuator have the functional modes of double acting and spring,and the spring return has the normal open and normal close styles

7) Multi-function position indicator with NUMER is convenient for mounting accessories

8) Pre-compressed load spring is convenient for safe mounting and tear down procedures.

9) Die-casting aluminum pistons and end caps have high intersity and light weight

10) Different O-rings material are available for high and low temperature

11) According to different demands we can offer multi-travel rotations(E.g 120 135 180)and three position actuators

12) Solenoid valves are easily mounted without any connecting plank

Operating conditions

1. Operating media

1) Dry or lubricated air,or inertia gas,which should be compatibl with inside parts and lubricator of the cylinder

2) The temperature of the operating media is a minium of -20ºC

3) The dimension pf the impurity particle is at the largest of 30u,if the positioner is needed,the dimension may be at largest of 5um

1. Air source pressure:3Bar-8Bar

2. Operationg temperature:

 Standard:-20ºC-80ºC

 Low temperature:-40ºC-80ºC

 High temperature:-20ºC-160ºC



* All listed output torques are expressed in inch pounds of torque (in. lbs.).
* Charts for available air pressure are expressed in pounds per square inch (P.S.I.).
* FLOWX actuators offer ±5° adjustment in the open and closed positions on DA52 through DA-125 models.
* For all other models, adjustment is in the open position only.
* The closed position is 0° fixed. Optional retrofit kits are available to allow for adjustment in both open and closed positions on the DA-160, DA-200 and DA-270 models.
