Advanced Actuation & Automation Processes in Gas Lines

Precision and safety are critical in the oil and gas industry. Automation using flow control valve actuators optimizes efficiency, modulates the flow of gas or liquid, increases safety for operators and decreases maintenance and operating costs over time. The automation industry has recognized that the function of actuators has moved beyond just opening and closing valves to providing key diagnostic and operational data via Bluetooth interfaces from sensors that measure pressure, torque and vibration. The types of actuators needed are dependent on a variety of factors.

Types of Valves

The types of valves controlled by the actuators determine the actuator used. The actuator must be matched to the following characteristics of the valves:

Function

Movement

Position

The frequency that the valves are used varies with the function of the valves. Those that open up or close off the flow completely for maintenance or safety reasons are used less frequently than those that continually modulate the flow of gas or liquid. Similarly, the movement of the valves varies with the type of valve, requiring actuation. Controls for ball valves require a swivel movement provided by a quarter-turn actuator, while a multi-turn actuator would enable the many turns required to open or close a valve.

Precision is key in oil and gas transmission and electric actuators can provide superior positioning accuracy. Position accuracy is important for control valves that modulate the flow during the various stages. From the initial flow of crude oil and natural gas to storage and transportation, then finally to the refining and distribution process, the valves modulate not only the flow rate and pressure through the various pipe diameters but the rate that the oil or gas is fed into the various processes along the way.

Processes

The more processes involved, the more actuators are needed to manage the complexity of the system. We recommend you work closely with your electric actuator manufacturer to help configure a solution that is right for your needs. Sensor technology has expanded the use of flow control valve actuators to allow for monitoring in real-time and integration into IIoT (Industrial Internet of Things). Much like the smart electronics being used in factories and homes, the controls for ball valves have embraced smart technology to deliver improved flow control. Integration with supervisory control systems enables next-generation processes such as asset management on a plant-wide scale and optimized maintenance control and scheduling. Integrated operations combined with wireless communication provide operational information at a faster rate, allowing more processes to be managed with fewer resources but with increased accuracy, efficiency and response time.

Selecting the Right Automation Solutions for Valves

Create a customized solution for your valve automation today. Whether you’re looking to update your current equipment or installing a brand-new valve that requires automation, compare these essential components for valve actuation and other automation solutions designed to streamline your process and improve your overall efficiency.

Linear Vs. Rotary Actuators

One of the most important factors in selecting the right automation is choosing between linear and rotary actuators. Linear actuators operate with pinch, gate and globe valves to create an efficient automated valve operation. Each of these options require movement in a straight line, so a linear actuator manipulates the valve in this pattern.

A rotary actuator works with different types of motor operated valves. These actuators produce more traditional rotational movements. Choose a rotary actuator if you need automation for your plug, ball or butterfly valves.

Comparing Power Sources

Once you’ve selected the ideal actuator movement, your controllers and positioners require a specific power source. Whether you’ve chosen linear or rotary actuators, select one of these reliable sources of power:

Electric

Hydraulic

Pneumatic

Electric is a popular option for custom linear actuators. It allows you to control your actuator with precision, requires a cost-effective maintenance schedule and is flexible enough to be used for a variety of industrial valves. However, heavy-duty valves require stronger electric motors, pneumatic power or hydraulic pressure for proper use.

Selecting Accessories

Finally, your valve actuator requires a series of accessories for precision performance. Pneumatic actuators in particular require solenoid valves, positioners and limit switches for safe and effective operation.

Solenoid valves are used as a pilot valve for your heavy duty linear actuator and other pneumatic rotary actuator designs. These control devices control the air pressure through either manual manipulation or electrical signal. When connected with the latest computer software, your solenoid valve will automatically adjust the pressure and timing of your pneumatic actuator for precision control of your valve.

A positioner is essential for throttling your air flow. Be sure your pneumatic positioner allows you the level of control and maximum air flow you need to operate your valve and accurately adjust the flow rate as necessary.

Finally, a limit switch is necessary for accurate control of your valve. Similar to an electrical actuator, a pneumatic actuator requires a limit switch to signal when you’ve reached the appropriate rotational point on your valve.
