  • Valve Actuators, Old and New

    The term valve actuator is likely to evoke images of automotive components for many people with backgrounds in industry, specifically those who have had experience in the automotive industry as professionals or as hobbyists. However, it may surprise some of those people to hear that actuators are used in the control of valves outside of the context of the automotive world. In these other contexts, valve actuators might not be used to the same extent as they are to close choke valves during an engine cold start, at least not...

  • Valve Actuators

    Valve actuators are devices that produce mechanical linear motion by converting various forms of energy into mechanical energy. Typically they are a part of motion control systems in processes that require automated assembly. These valves are one of either three types which include hydraulic, electric, or pneumatic. They are selected for use based on the job that they need to be able to perform. Valve actuators are found to be controlled by computers most of the time however some simple application actuators can even be powered manually by hand. Some...

  • New Anti-Rotational Design Ensures Actuator Accuracy

    BEI Kimco, a brand of Sensata Technologies, has introduced a new moving magnet Voice Coil Actuator with a flexure design that ensures high alignment accuracy by preventing unwanted shaft rotation. The new VCA also provides long life with cost-effective pricing and is ideally suited where extreme precision is required, such as in medical equipment, laboratory instrumentation, clean rooms, low-outgassing and aerospace applications. The Housed Linear Actuator Model LAH13-11-000A incorporates a shaft with flexures at both ends of travel that support the moving magnet field assembly. In addition to preventing shaft...

Industry Information

Valve Actuators

Valve actuators are mechanisms that provide linear movement to valves through the use of various screw assemblies. This movement is typically utilized to position the valve as well as to open or close the valve, depending on the application. A broad range of valves that valve actuators are used for include metering valves, needle valves, globe valves, diaphragm valves, gate valves, pinch valves and angle valves.

Due to the extensive variety of valve types, valve actuators are used in diverse industries such as: chemical processing, for fluid processing and flow control applications; wastewater and water treatment, for pressure regulation as well as in flood prevention equipment; industrial manufacturing, for process automation applications; petroleum, in gas transmission pipelines; and automotive, for applications such as valve positioning and actuation in camless engines. Additional industries include pharmaceutical, power generation, marine and aerospace. Some advantages that valve actuators offer include accurate proportional control, rapid flow control and automated valve control allowing for increased efficiency. While valve actuators can be rotary or linear, linear valve actuators are beneficial for use in applications requiring tight operational tolerances.

Linear valve actuators achieve linear motion through the use of screw assemblies, the two main types of which are lead screw and ball screw. Lead screws, also referred to as power or translation screws, are threaded rods designed to translate rotational movement into linear motion. Ball screws accomplish the same linear motion, however they offer reduced friction due to a ball that is encased within the round nut. Valve actuators can provide actuation through several different methods: manual, electric, pneumatic, hydraulic and solenoid. Manual valve actuators can be either manual handwheel or manual level. Manual handwheel are more common, but they do not allow for automated valve operation.  Electric valve actuators utilize motors, typically DC motors, in order to allow for manual, semi and fully-automatic valve operation. Electric valve actuators operate by providing mechanical force through the conversion of electrical power. Pneumatic and hydraulic valve actuators can provide semi and fully automated valve operation as well; however, pneumatic valve actuators are utilized in air pressure applications, whereas hydraulic valve actuators are utilized in water and other fluid pressure applications. Solenoid valve actuators are the most recent technology, but they are more strictly limited to simply opening and closing the valves.
