Product Description

3 Position Pneumatic Actuators Dosing, Exact Filling On 90° Rotation An Intermediate Stop Position

 

Description of Product

Pneumatic valve actuator which compact design, long life service, high quality, gear and gear rack.

This product is used for 90° Rotationally valves, such as: Ball vales, butterfly valves, plug valves etc. My company put product

Quality as the first task, adopts the most advance production and technology, strong than similar product on both product quality and performance.

Air operated actuator is the compact, the life is long, the quality is high, rack's-like air operated actuator.

 

 

3-position (90° rotation) 3 position pneumatic actuators provide an operation of 0°- 45°- 90°. the intermediate position is achieved by an external mechanical stop of movement on the 2 auxiliary pistons (for spring return actuators it may be only one auxiliary piston). this intermediate stop position is adjustable from 0° to 90°, for example 5°, 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.
in order to control the operation of air torque 3-position pneumatic actuators a system of solenoid
valves controlling a sequence of air supplies to the actuator is required as described below:
when ordering 3-position pneumatic actuators, add “3p” to the normal
actuator code and specify the desired stop position including the intermediate e.g. 0° - 45° - 90°.
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.
