Valve Automation is recognized worldwide for the reliability of its actuators under the most demanding conditions. The gas/hydraulic products epitomize the quality and performance required for controlling high pressure natural gas pipelines in remote locations and under severe climatic conditions.Bettis gas/hydraulic actuators are used to automate valves located on gas transmission pipelines, often travelling hundreds of miles through remote areas, where there are no low pressure instrument air or high pressure hydraulic supply lines available.The gas/hydraulic actuators operate using pressurized gas from the pipeline as its power source, requiring reliability and safety features built into the valve operator system. Since the line gas is a potential hazard, Bettis actuators use a clean, nonexplosive hydraulic fluid as an oil barrier rather than direct line gas.
Some of the salient features include High torques and thrusts. Rotary quarter-turn models have torques upto 6,000,000 lb. in (678,000 Nm)and linear models with thrusts up to 650,000 lbs(2,891,200 N). They are most adaptable for all types of gas compositions including sour(NACE)and wet gas. Standard operating temperature is -50°F to 150°F (-46°C to + 66°C)and Standard operating pressure is upto 1,440 PSIG.
