AT pneumatic actuator - Type - Aluminum - Size

AT pneumatic actuator Product: AT pneumatic actuator details actuator pneumatic actuator and adjustment mechanism is a unified whole, which has a film executive body, piston, fork-type and rack and pinion. Piston stroke length, for applications that require a greater thrust of the occasion; and thin Product Specifications: Model: AT50-300 Material: Aluminum Size: 50-300 Product Details AT pneumatic actuators pneumatic actuators details actuator and control organization is a unified whole, its executive body with a thin film, piston, fork-type and rack and pinion. Piston stroke length, for applications that require a greater thrust of the occasion; and thin-film small stroke, can only directly contributing to the valve stem. Scotch yoke pneumatic actuator has torque, small space, more in line with the valve torque curve torque curve characteristics, but not very beautiful; commonly used on high torque valves. Rack and pinion pneumatic actuator has a simple structure, stable and reliable operation and safety explosion-proof, etc., there is a wide range of applications requiring high security production plants, chemical, oil refining and the like. Pneumatic actuator is driven by gas pressure regulating valves open and close or actuators, also called pneumatic actuators or pneumatic means, but most popular is called the pneumatic head. In this paper, various technical requirements for pneumatic head elaborate. AT series of new pneumatic valve actuators AT new rack and pinion pneumatic actuator is driven by what the company Shanghai combines the latest technology at home and abroad, through the innovative three-dimensional CAD model to optimize the design, appearance compact, modern style; and the use of practical new materials, new processes, product quality, more reliable performance; multi-standard selection of more affordable; products fully comply with the latest international standard specifications to meet current and future needs. ① symmetrical dual piston rack and pinion design, operation fast and smooth, high precision, high output power, by simply changing the rotational position of the piston assembly in the opposite direction can be obtained. ② quality extruded aluminum alloy cylinder block, through the hole and the outer surface of the precision machining of hard anodized (under special circumstances anodized + Teflon coating), longer life, low coefficient of friction. ③ one design, all double-acting and single-acting actuators models have the same block and cover, very convenient by adding or removing springs to change the mode of action of the spring. ④ combined pre-spring break Hean whole group, both in the assembly process or the use of the site, and can be easy and safe to install or increase or decrease the number of springs. ⑤ external side of two separate adjustment screws for already installed on the valve actuator is to facilitate accurate, the valve opening and a valve closed position, while For full stroke adjustment is additionally configure a longer adjustment screw at the two end caps. ⑥ Multifunction position indicator, a visual indication of the site, in line with VID / VIE3845, NAMUR standard slot, and outputs can be installed all accessories, such as limit switch box, electric positioners, position sensors (Fuchs, Turck). ⑦ air interface complies NRMAR standard, can be installed directly NUMAR standard solenoid valve. ⑧ rack on the back of composite bearings and piston guide ring and the output shaft bearings prevent metal-to-metal friction and increase lubrication, making it a low friction, long life. ⑨ All fasteners are made of stainless steel, long-term corrosion resistance. ⑩ connection portion in line with new international standards ISO5211, DIN3337 (F03-F25) so that production installation with interchangeability, versatility. AT-DA double action works when air pressure into the cavity between the two piston cylinder from the air inlet (2), so that the two separate piston moves opposite ends of the cylinder, the air is discharged through the ends of the gas chamber air inlet (4), while the two pistons rack synchronous drive counterclockwise rotation of the output shaft (gear). Conversely air pressure into the cylinder chamber from both ends of the gas inlet (4), the piston moves in the cylinder so that the two intermediate direction, the air in the middle of the gas chamber (2) is discharged through the air intake, while the two pistons rack synchronous drive output shaft (gear ) clockwise rotation. (If installed in the opposite direction of the piston relative to the output shaft turns counter-rotating, that is double role reversal DL type) air into the left holes, drive around the piston push air into the right holes, drive to the middle of the compression piston. AT single action When the pneumatic actuator works When air pressure from the air inlet (2) into the cavity between the cylinder pistons, piston so that the two opposite ends of the cylinder separate move, forcing the ends of the compression spring, both ends of the air chamber through the air inlet ( 4) discharge, while the two pistons rack synchronous drive counterclockwise rotation of the output shaft (gear). After the gas supply pressure solenoid valve commutation, two cylinder piston moves in the direction towards the middle of the spring tension, the exhaust air from the middle of the gas chamber air intake (2), while the two pistons rack synchronous drive output shaft (gear) clockwise rotation. (Output shaft turns in the opposite direction if the piston relative to the installation, when the reverse rotation spring return, is the single role reversal SO type) Order by: This product is factory direct supply products, for special configuration (can be customized). Please specify when ordering the following parameters: (example: valve type, drive type, connection type, structure type, nominal pressure, nominal diameter, the input signal, the sealing surface material, body material, suitable temperature, with or without attachments) Contact Inquiry Price ----> OK price ----> Fax contract ----> contract ----> Pay deposit ----> deliverables ----> settle payment
