Wenzhou supplier Three Position 3-Position Pneumatic Actuator
General application
The aluminum Rack & Pinion actuator has all features required to operate both ball and butterfly valves in all general process applications ranging from building services and water applications to petrochmical applications.Wenzhou supplier Three Position 3-Position Pneumatic Actuator
Its compact design makes it specifically suitable for applications with limited space availability and weight restrictions.
 
3-Position pneumatic actuators provide an operation of 0°- 45°- 90°or 0°- 90°- 180°. The intermediate position is achieved by an external mechanical stop of movement on the 2 auxiliary pistons. This intermediate stop position adjustable e.g. 90° actuators can provide 20°, 30° 50°, 75° etc. The intermediate position is easily achieved by adjusting the external nuts located outside the two end-caps. 

Both type, double acting and spring return, are available. Field of application: For dosing, for exact filling and for any kind of services where on 90° rotation an intermediate stop position is desired.
 
Position 1 (Intermediate Position):
This position is achieved when air is supplied simultaneously to ports 2 and D whit exhaust air at ports 4 and C. In fact the air supplied at ports D forces the auxiliary pistons to the center and the rods serve as mechanical stops for the internal pistons stopping in the desired intermediate position.
 
Position 2 (Fully Open Position):
This position is achieved when air supplied to port 2 and port C (Air to port C may also be avoided) with exhaust air at port 4. In this condition air to port 2 permits air to the internal pistons to continue the opening stroke.
 
Position 3 (Fully closed Position):
This position is achieved when air is supplied to port 4 with exhaust air at port 2.
