VCTDS-02952-US FeatureS • t otally enclosed, weatherproof housing in fabricated carbon steel for maximum strength. • Guide bar resists transverse loads and supports the piston rod. • Hard chromium plated alloy steel material guarantees corrosion protection and minimal friction. • Pt FE-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 between 82° and 98°. • Electroless nickel plated and polished cylinder provides maximum corrosion resistance and reduces friction. • t riple-element piston seals provide low friction, high sensitivity, ensure long life and prevent sticking problems. • OLGAS-H fully encapsulated spring return pack ensures personnel safety and simplifies assembly. General application • OLGAS-H modular design enables spring action to be changed in the field easily. • OLGAS-H QA achieves ‘safe’ position in 0.2 second. OLGA-H and OLGAS-H series hydraulic actuators are designed for the control of quarter turn ball, butterfly, plug or damper style valves.
