The oil and fuel industry has become one of the most dominant in the world in recent years. For example, according to IBISWorld, about 213,163 Americans work in the oil, gas, and pipeline construction industry. Many make products like DynaTorque actuator valves. If you have never heard of these products, it's important to know what they do and how they help your firm.

What Is a Valve Actuator?

A valve actuator activates or moves a valve from open to closed positions and vice versa. It attaches directly to the valve body and pilot and works with them, helping them operate smoothly and efficiently. The two common types are pneumatic and electrical actuators.

Both valve types do the same thing but work slightly differently. The pneumatic actuator uses pressure to open and close valves, while the electrical model uses a motor. The type you prefer will vary depending on your pipelines and the processes you use in your facility.

What Are Their Parts?

A DynaTorque valve actuator includes several different parts, including an adjusting screw, breather plug, spring, bonnet, stem, and diaphragm assembly. Each of these parts does something different on the actuator to help it operate smoothly. Let's break them down to show you how they work.

The adjusting screw puts pressure on the spring to keep the valve in its fail position. The diaphragm moves with the spring while maintaining pressure to help adjust its position. The breather plug lets the opposite diaphragm end move freely and prevents it from getting air locked.

The assembly bolts directly on the valve body to help provide extra support and structure. The bonnet and stem also help to support the valve actuator and control the diaphragm and spring. As pressure changes within the actuator, these parts work together to control oil and gas flow.

Parts like the pilot and control valve help manage flow through the pipe. The pilot senses pressure and either tells the actuator to open or close. The control valve sits under the actuator to receive signals from the pilot and physically pushes on the diaphragm to control it.

The importance of using a DynaTorque actuator valve properly makes it critical to work with a team you can trust. Contact Hi Teck Valve Inc today to learn more about these items and how they benefit you. Our crew will give you the inside scoop and ensure that you better understand how they work.
