Burkert Case Study: Reduce Energy Costs wi­­th Digital Valve Positioners

Traditional pneumatic top mount valve positioners with I/P transducers have remained a staple in the food and beverage industry for almost 70 years. The advantage has been the durability of an all-mechanical system in an environment subjected to constant washdown. But, we will introduce to you a way you can reduce energy costs with a digital valve positioner. Here’s how!

The Problem

The downside to this device is the numerous valves and springs inside the housing and the fact that this device is designed to leak air continuously.

The Solution

The Burkert Digital Valve Positioner eliminates these air losses. The correct amount of air is injected into the actuator chamber so that the valve is set at the required position.

Electronic solenoids control the air flow in and out of the actuator chamber. The firing of the solenoids is controlled by a sensing puck in conjunction with an internal PID controller.

  • Pneumatic positioners bleed air continuously. Digital positioners use no air once set-point has been achieved.
  • Electronics enclosure is pressurized with the instrument air during modulation to keep moisture out.
  • Adaptable to most linear actuated valves
  • Compressed air can cost up to 8 times more than electricity. Save air, money, and energy using a digital valve positioner!
