Hydraulic Actustors
VCTDS-02815-US
FeatureS • Totally 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. • 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 between 82° and 98°. • Electroless nickel plated and polished cylinder provides maximum corrosion resistance and reduces friction. • Triple-element piston seals provide low friction, high sensitivity, ensure long life and prevent sticking problems. • OLGAS fully encapsulated spring return pack ensures personnel safety and simplifies assembly. General application • OLGAS modular design enables spring action to be changed in the field easily. • OLGAS-QA achieves ‘safe’ position in 0.2 second. OLGA and OLGAS series hydraulic actuators are designed for the control of quarter turn ball, butterfly, plug or damper style valves.
