Reduced Energy Costs with Digital Valve Positioners
Compressed air can cost up to 8X more than electricity. Save air, money, and energy using a digital valve positioner.
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 the all mechanical system in an environment subjected to constant washdown. 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... transition from pneumatic positioner to digital positioner
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 in order to keep moisture out
• Adaptable to most linear actuated valves
