• Guide bar resists transverse loads and supports the piston rod.
• Hard chromium plated alloy steel material guarantees corrosion protection and minimal friction.
• PTFE-impregnated bronze or sintered bronze bushings provide minimal friction and extended service life.
• Scotch yoke design with canted or symmetric torque arm allows close working to distinctive valve torque profiles.
• External travel stops for precise angular stroke adjustment 90 degrees +/- 4 degrees at each end of travel.
• Electroless nickel plated and polished cylinder provides maximum corrosion resistance and reduces friction.
• Floating type piston seals provide low hysteresis and high sensitivity, preventing sticking problems.
• ALGAS Spring-Return pack incorporates up to four springs, fully encapsulated in a factory welded cartridge ensuring personnel safety and simplifying assembly.
• ALGAS spring action can be changed easily in the field from to close to open or vice versa.
