3.Multi-specification products make selection more economical.
4.Innovative, patented, universal output shaft and multi-function indicator
5. Fully meet the latest international regulations
6, widely applicable high-level surface anti-corrosion technology
7, beautiful compact and modern shape.
Air Torque Product Structure
1. Aluminum extrusion prevents internal and external corrosion, a longer service life, and a lower surface friction coefficient.
2. Double-piston rack-and-pinion design has compact structure, symmetrical installation position, high cycle life and fast operation. Reversal can be done with a simple reverse piston.
3. Two independent external stop adjustments allow easy and precise adjustment of +/- 4 in both directions. This adjustment may be in the open or closed position and provides accurate valve alignment.
4, universal a simple conversion, from the parallel diagonal square, reverse drive shaft. This feature allows a lower and more flexible frame. The double-sided universal design is available as a fourth-generation option and power technology standard, and can be easily adapted to any valve.
5. Use a single compact design for the same style and end cap for double acting and spring. This feature reduces inventory and field conversions, and can be added or removed via a modular spring box.
6. Visual position indication and direct, convenient and economical way to install multi-function position indicator of popular sensors.
7, multiple bearings and pistons and precise operation, low friction, high cycle life and precise pinion shaft bearing guidance.
8. Modular pre-assembled spring box with universal design in simple range, higher safety and corrosion-resistant coating spring design
9. The precise positioning of the piston rack and pinion shaft, low gap, and the largest fully processed tooth caused by the overall efficient operation.
10. Chemically nickel-plated steel wire, guide bearing, single piece pinion shaft with improved safety and cycle life.
11. Select high-quality bearings and seals to provide a wide operating temperature range, low friction and high cycle life.
12, internal and external long-term corrosion-resistant stainless steel fasteners.
13. ISO 5211, DIN 3337 and VDI / VDE 3845 certifications for product interchangeability and easy-to-install solenoid valves, limit switches and other accessories.
① The double-piston symmetrical structure design of the rack and pinion has fast and stable action, high precision, and high output power. It can be rotated in the opposite direction by simply changing the assembly position of the piston.
② The extruded high-quality aluminum alloy cylinder body is hard-anodized by precision machining of the inner hole and the outer surface (anodic oxidation + Teflon coating in special cases), with longer service life and low friction coefficient.
③ Integrated design, all double-acting and single-acting actuator models have the same cylinder body and end cover, which is convenient to change the action mode by adding or removing springs.
④The combined pre-load safety spring set can be easily and safely installed or increased or decreased in the assembly process or in the field of use.
⑤ Two separate adjustment screws on the outer side are more accurate and convenient for the actuators already installed on the valve. Adjust the valve opening and closing positions. If full stroke adjustment is required, additional adjustment screws are provided at the two end covers.
⑥Multi-function position indicator, on-site visual indication, conforming to VID / VIE3845, NAMUR standard slot, can install and output all accessories, such as limit switch box, electrical positioner, position sensor (Pepperl + Fuchs, Turck).
⑦The air source interface complies with the NRMAR standard and can be directly installed with NUMAR standard solenoid valve.
复合 The composite material bearing bush and piston guide ring on the back of the rack and the bearing of the output shaft are used to prevent metal-to-metal friction, and to increase lubrication, so that it has low friction and long life.
⑨All fasteners are made of stainless steel for long-term corrosion resistance.
⑩The connection part complies with the new international standard ISO5211 and DIN3337 (F03-F25), which makes the production and installation interchangeable and versatile.
