Application
The angular stroke cylinder piston actuator is suitable for A400, A450, A760, A770, A780and A790 series control valves. Single-acting model: 833, double-acting model: 834
Features
· The combination of piston rod and guide rod with excellent surface treatment and self-lubricating bearing, ensuring excellent wear resistance and extending the service life of sliding parts
· Nickel, chrome or PTFE coating on the inner wall of the cylinder; enhanced wear resistance and anti-corrosion/electrostatic spraying on the surface meeting the requirements of petrochemical and chemical industry
· Driving device consisted of transmission, cylinder, spring and side attachment modules, featuring convenient disassembly, replacement and fewer inventories
· Reliable. Removal of the safety spring module as a whole from the driving device along the axis of the cylinder module only, avoiding damage of spring force to people and the driving device
· Featuring quick-opening and quick-closing, compatible with manual operating mechanism/various control accessories
