Blac Inc. Electro-Hydraulic Actuator

Manufacturer: Blac Inc.

BLAC INC. engineers and constructs the highest quality electro-hydraulic linear or rotary output actuators, hydraulic controls, and hydraulic power units for industries throughout the world. Our actuator systems deliver reliable long term continuous operation, unique features, and ease of maintenance.

BLAC INC. products are developed for severe service applications that can cause other equipment to fail, such as:

  • Low or High Temperature Ambient Conditions
  • Environments Highly Contaminated with Dust, Catalyst, Coke Fines, Fly Ash, Corrosion or Acids
  • High Humidity
  • Severe Vibration

Using state-of-the-art components and construction methods, BLAC INC. personnel engineer all equipment with computer aided design, 3-D modeling, computer controlled machining centers, and in-house quality control from start to finish.

Industries Serviced

Fluid Catalytic Cracking Unit Applications on All Major Licensee Operating Units

Recognizing that the unexpected does happen (and components do fail), BLAC INC. realistically approaches systems design. Our mission is to design systems that provide continued process unit operation if major components are damaged or lose functionality.

Because of our no-nonsense methodology, BLAC INC. is the premier supplier of slide, plug, and butterfly valve actuator systems worldwide for FCCU applications on All Major Licensee Operating Units. The BLAC INC. systems are proven to provide long term reliability, accuracy, and true redundancy of components to handle the situation when the unexpected occurs.

Boilers

BLAC INC. actuators improve process control efficiency by controlling accurately to the command setpoint.

If the existing process is controlled to +/- 3.0% (because of inaccurate actuator response), then the improvement that comes from the control of 0.1% is dramatic.

Effectively, boiler oscillations are reduced by 2.9% for this example — providing significant improvements.

  • Induced Draft and Forced Draft Dampers
  • Primary and Secondary Air Flow Control Dampers
  • CE Boiler Corner Fired Tilt Drives
  • Reheat and Superheat Spraywater
  • Fuel Gas and Boiler Feedwater Regulation Valves
  • Startup Valve Actuator Systems
  • Selective Catalyst Reduction Inlet, Outlet, and Bypass Dampers
  • Fluid Coupling Modulating Drives
