Double Acting or Single Acting Aluminum alloy pneumatic actuator, Aluminum alloy pneumatic actuator

 

Pneumatic actuator works: When the compressed air nozzle into the tube from A pneumatic actuator, the gas piston to push both ends of double (head end) a straight line, piston drive rack gear counter-clockwise rotation axis 90 degree, he incurs the valve open. At this point both ends of the gas valve pneumatic tube nozzle discharge with B. Conversely, when the compressed air nozzle from B officer to enter the two ends of the actuator, the gas plug to the center to promote the dual linear motion, piston rack gear driven rotary shaft rotated 90 degrees clockwise, close the valve incurs . At this point the middle of the actuator nozzle of the gas discharge tube with A. The above standard transmission theory. According to user needs, pneumatic actuator can be installed into a standard reverse gear with the principle, that selecting the right shaft clockwise to open the valve counter-clockwise to close the valve. Single acting (spring return type) A pneumatic actuator nozzle to the inlet tube, B is the vent tube nozzle (B muffler pipe nozzle should be installed). A nozzle inlet pipe to open the valve, cut off the gas when the valve closed by spring force.

Pneumatic actuators advantages:
1, to accept a continuous air signal, the output linear displacement (power / gas conversion device, can accept a continuous signal), and some accompanied by arm, the output angular displacement. 2, there is, counter-productive functions.
3, big speed, but slows down when the load increases.
4, the output power and operating pressure.
5, high reliability, but the gas valve can not maintain the source after the interruption (plus insurance valve position can be maintained).
6, the inconvenience to achieve sub-control and process control.
7, repair and maintenance is simple, good adaptability to the environment.
8, the output power is larger.
9, with explosion-proof function.

Pneumatic Actuator features:
1 compact dual-piston gear, rack structure, precision engagement, high efficiency, constant output torque.
(2) aluminum cylinder block, piston and end caps, with the same specifications than the weight of the structure of the lightest actuator.
3 cylinder is extruded aluminum, and by the hard-anodized, hard inner surface texture, strength and hardness. Low-friction material sliding bearings, avoiding direct contact between the metal between the low coefficient of friction, rotational flexibility, long service life.
4 pneumatic actuator and valve installation, connection dimensions according to international standard ISO5211, DIN3337 and VDI/VDE3845 design, can be interchangeable with ordinary pneumatic actuator. 5 air holes in accordance with NAMUR.
6 pneumatic actuator shaft bottom hole assembly (in accordance with ISO5211 standard) dual square, easy party lever valve with linear or 45 ° corner installation.
7 the output shaft at the top and the top of the hole in accordance with NAMUR.
8 at both ends of the adjustment screw to adjust the valve opening angle.
9 have the same specifications double-acting, single acting (spring return).
10 can be selected according to the direction of the valve, clockwise or counterclockwise rotation.
11 according to user need to install the solenoid valves, positioners (opening instructions), reply, a variety of limit switches and manual devices.
