Tips: Pneumatic valve actuator working principle

When the compressed air enters the pneumatic actuator from the A nozzle, the gas pushes the double piston to move linearly to both ends (cylinder head end), the rack on the piston drives the gear on the rotating shaft to rotate 90 degrees counterclockwise, and the valve is opened. . At this time, the gas at both ends of the pneumatic actuator valve is discharged with the B nozzle. On the contrary, when the compressed air enters the two ends of the pneumatic actuator from the nozzle B, the gas pushes the double plug to move linearly to the middle, the rack on the piston drives the gear on the rotating shaft to rotate 90 degrees clockwise, and the valve is closed. At this time, the gas in the middle of the pneumatic actuator is discharged with the A nozzle. The above is the standard transmission principle. According to the user's needs, the pneumatic actuator can be installed in the opposite transmission principle to the standard type, that is, the clockwise rotation of the selected shaft is to open the valve, and the counterclockwise rotation is to close the valve. The single-acting (spring return type) pneumatic actuator A nozzle is the air inlet, and the B nozzle is the exhaust hole (the B nozzle should be equipped with a muffler). The inlet of the nozzle A is to open the valve, and the valve is closed by the spring force when the gas is cut off.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
