Description

Pneumatic actuator parameters

Indicator Position indicator with NAMUR is convenient for mounting accessories such Limit Swich box
Pinion The pinion is high-precision and integrative,made by mickelled-alloy steel,full conform to the lastest standards of ISO5211,DIN3337,NAMUR.
Cylinder ASTM6005 die casting aluminum alloy cylinder block, the hard oxide
End caps Die-casting aluminum powder spraying a variety of colors
Pistons Double piston rack, the rigid aluminum oxide, symmetric mounting position, fast operation, long service life, simple reversal of piston can change the direction of rotation.
Travel adjustment Two independent stroke adjustment screw can be convenient, accurate to 5 ° ± regulation, position.
Spring High performance spring using quality materials, coating, preloading assembly. Removing single simple actuator, by changing the spring quantity to meet different torque output range.
Bearing Bearings, guide: Using low friction, long-life compound material, to avoid the direct contact between metals, repair and replacement are easy and convenient.
Seal Normal use of nitrile rubber. High or low temperature by fluorine rubber or silicone rubber
Control Double acting, single acting
Annex Reversing solenoid valve, limit switch back to the hearing, the electrical positioner, hand wheel mechanism
