(Pneumatic Actuator)
APA Series Of New Valve Pneumatic Actuator
-
Intro
APA new rack and pinion pneumatic actuator by the zhejian AVTEC company combines the latest technology at home and abroad, through the three-dimensional model of innovation and optimization of CAD design, beautiful shape compact, modern styling; and adopt practical new materials, new processes, so that the product quality, more reliable; more standard selection of more affordable; products fully meet the latest international standards technical specifications, to meet current and current and future needs. -
① Dual Piston Rack and Pinion
Dual piston rack and pinion design of symmetric structures, rapid and smooth movement, high precision, high output power by a simple change in the direction of the piston assembly positions available anti-rotation. -
② Extrued Aluminum
High quality extruded aluminum alloy cylinder block, by precision machining the hole and the external surface of hard anodized (anodic oxidation under special circumstances + Teflon coating), longer life, low friction coefficient. -
③ Intergrated Design
Integrated design, all the double acting and single-function actuator models have the same cylinder and end caps, easily removed by installing a spring or spring to change the mode of action. -
④ Combined Pre-Spring
Combined pre-spring break Hean whole group, whether in the assembly process or use on-site in both convenient and safe to install or change the -
⑤ Independent Adjustment Screw
The external side of the two single independent adjustment screw has been number of springs. installed in the valve for the actuator is precisely to facilitate, control valve open and valve closed position. For the whole trip conditioned office is also configured in two cover a longer adjustment screws. -
⑥ Multi-Position Indicator
Multi-position indicator, on-site visual instructions, consistent with VDI/VED3845, NAMUR standard slot, the output can be installed and all the accessories, such as limit switch box, electric positioner, position sensor(Pepperl and Fuchs, Turck) -
⑦ Standard & Safe Gas Source Interface
Gas source interface line NAMURstandard, direct safety plaquesNAMUR standard solenoid valve. -
⑧ Long Life
Rack on the back of the composite bearing and piston guide ring and the output shaft bearings to prevent metal on metal friction and increasing lubrication, so a low friction, long life. -
⑨ Fasteners Stainless Steel
All fasteners are stainless steel, long-term corrosion resistance. -
⑩ International Standard
Connection part of the line with new international standard ISO5211, DIN3337 (F03-F25) makes products with interchangeable, versatile.
