pneumatic actuator for ball valve butterfly valve
1.hard anodizing treatment
The cylinder body has been treated with hard oxidation,the hardness is higher than normal one.Its durability extends the service life.
2.cylinder body screws are made of German stainless steel.Fine workmanship,guaranteed quality.
3.hard anodizing treatment for piston
The piston in the cylinder block is also treated by hard oxidation,and the deepening of the plug groove further fixes the screw device,thus avoiding the displacement and loosening of the spring during use.
Extrusion manufacturing,extruded aluminum molding in one time.
2.anti-corrosive and wear-resistance
The surface of whole cylinder is treated by Alodur+Teflon which is suitable for chemical workshop and seaside conditions,etc.
Suitable for petroleum,metallurgy,power sector,paper making,new energy,hydraulic etc.
Easy to use,rapid on-off
