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.

• Polytetrafluoroethylene (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° ± 4° at each end of travel.

• 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.

• OLGAS modular design enables spring action to be

changed in the field easily.

• OLGAS-QA achieves ‘safe’ position in 0.2 seconds.
