Deskripsi Produk Pneumatic Actuator :
- Indicator
A. position indicator with Namur mounting is standart on all HAITIMA pneumatic actuators mounting acessories - Pinion
The hardened alloy steel pinion is precision ground and Nickel plated ( over 25um) in order to reduce friction, provide maximum wear resistance. Full conformance with the newest standards of ISO5211 & DIN3337. The dimensions can be customized and as options, stainless steel and aluminium are also available. - Actuator Body
The aluminium extrusion is hard anodized ( over 30 um ) to protect agaonts wear and corrosion while reducing piston friction to the absolute minimum. Other options sunch as Nickel plating, PTFE and powder polyester painting are available. - End Caps
Epoxy coated ( over 150 um ) die cast aluminium end caps provide maximum resistance against potentially corrosive element. Other treatments such as nickel plating & PTFE painting are available
Sizing Example of Nutork double acting actuator : valve torque 100Nm plus 20% safety factor = 120 Nm. Minimum operating pressure 6 bar (87psig0. By reading down the 6bar (87psing) column the figure below 120Nm is 135. ONm, the model number shown in the hand column is therefore NKD-029. Air to fort A forces the pistons outwards, causing the piston to trum counter-clocwise while air is being exhausted from port B. Air to port B forces the pistons inwards.
