Industrial valve actuators are available in an uncountable range of types, styles, power ranges, and feature sets to meet the needs of industrial processes everywhere. Some applications have a requirement for the control and decision making equipment or personnel to know the valve position at all times, including when operating power may be interrupted. This scenario calls for an absolute encoder with a battery backup.

An absolute encoder assigns a unique identifier to every possible shaft position, so any reading of the encoder value will indicate the current shaft position. These devices have historically been rather complex, but Rotork has developed a radically simplified approach that provides good operability while extending the useful life of the mechanism.

The short video below illustrates the primary features of the system. More information is available from product application specialists. Share your valve actuation challenges with them, combining your process expertise with their product knowledge for the best process control solutions.

Some industrial process applications are so demanding or specialized that custom, or semi-custom, products are needed to meet requirements for safety and performance that are beyond the realm of familiar product offerings. The requirements may involve the size, capacity, or particular arrangement of a component. Also, levels of risk aversion, safety, and redundancy may be a major factor in the performance requirements of a critical control element or equipment unit.

Some industries employ processes that involve the large scale control of energy. Keeping that energy under control and directed toward process completion is key to maintaining operational, financial, and safety goals. When the energy is associated with a fluid, valves of various types are employed to properly regulate and direct its flow. The control element for a valve is the actuator, which itself is driven by a controller, and all of which must together be capable of positioning the valve trim under all possible operating conditions.

 MEA is an industry leader in the design and manufacture of valve actuation systems safeguarding critical flow processes that include...

  • FCCU (Fluid Catalytic Cracking Unit) Slide Valves
  • Coker Switch Valves
  • Boiler and Furnace Damper Drives
  • Butterfly Valves
  • Plug Valves
  • Blower and Compressor Surge Controls
  • Wet Gas Compressor Controls
  • Oil Flow Control Valves

The company's most recently developed systems effectively eliminate unplanned shut downs by providing digitally controlled redundant actuators with 100% reliability and continuous control over connected valve actuators. MEA systems are easily integrated into existing networks and provide multiple levels of security and diagnostics.

MEA provides control systems and actuation solutions across several industrial sectors, including:

  • Refining
  • Utilities
  • Steel Production
