Fork type structure, suitable for high opening torque angular stroke (90°) valve drive.
The actuator ensures lasting operation with the help of the bushing, in particular:
-2 strong bronze support bushings * minimize friction and improve fork rotation accuracy.
-2 sliding bronze bushings increase the load area and reduce wear between fork and slider.
-2 guide blocks and bushings (sintered bronze and PTFE) on the piston rod increase efficiency, reduce maintenance and guarantee a long service life.
The guide bar can withstand high side forces and ensure adequate support.
All drive and piston rods are chromium-plated, thus ensuring maximum corrosion resistance and minimizing friction between the dynamic seals and their corresponding guide bushing.
PTFE filled graphite piston guide reduces friction between piston and inner cylinder surface, self-lubricating and maintenance-free.
The inner surface of the cylinder provides high reliability and corrosion resistance with a nickel coating.
Multiple external bolt structures ensure a solid cylinder block.
Carbon steel welding of the cylinder block provides maximum impact and stress resistance.
The inner coating (cylinder block and connecting block) provides corrosion protection.
Parts are made of no cast iron material to ensure its robustness and reliability.
The standard external coating is over 200 microns thick and protects the actuator from atmospheric interference.
External mechanical limits allow precise rotation adjustments of +/-5° in the on and off positions.
Low hysteresis and high reactivity make the actuator suitable for on/off and regulating functions.
Single acting pneumatic actuator can realize "fault off" or "fault on".
The spring group is completely sealed by initial welding to avoid any danger during assembly and use.
The actuator is connected to ISO 5211 and the attachment with stainless steel connector is fixed according to VDI/VDE3845 NAMUR.
