Linear gas-over-oil actuators are designed to operate rising stem valves using direct pipeline gas for on/off control of any natural gas transmission valve utilizing a high-pressure natural gas or nitrogen supply.
The ATI Quarter-Turn Gas-Over-Oil valve actuator is designed to operate using direct pipeline gas with pressures up to 1500 psi, providing torque outputs over 1 million inch-pounds. The design utilizes a proven canted scotch yoke actuator with dual oil tanks. With the cylinder always immersed in oil, the Gas-Over-Oil actuator provides maintenance free, long cycle-life actuation. The control modules can be used with the actuator to implement various valve control strategies.
