Control Valve Technology – Major Brand Comparison

Control valves play a crucial role in regulating fluid flow in a wide range of industrial processes and building systems. Without these cleverly engineered devices, it would be exceptionally difficult to achieve the level of precision process control that we often take for granted.

This article will explore some of the most technologically advanced control valve products from leading manufacturers Belimo, Honeywell, Johnson Controls, and Siemens.

We’ll look at how innovations in valve design, smart actuators, and digital analytics are enabling greater efficiency, more effortless connectivity with automation systems, and valuable insights into valve and process performance.

Whether quietly optimizing flows in an office air conditioning unit or enabling a manufacturing plant to achieve complex chemical reactions, control valves are the unsung heroes that lie at the heart of so many of the engineered systems we rely on.

This article will provide an overview of some of the most ingenious modern control valve technologies that help make our built environment operate more efficiently.

Belimo Products

As a pioneer in HVAC field devices, Belimo places a strong emphasis on innovative control valve technologies that set new standards for performance and reliability. A key product range is their line of globe valves engineered specifically for precise flow control and low noise emission.

Available in a range of body materials including brass, stainless steel and PVC, Belimo globe valves feature superior metering characteristics enabled by the company’s ultra-precise plug and seat machining capabilities.

They also offer an extensive range of butterfly and ball valves optimized for tight shut-off, robustness, and high flow rates.

One of Belimo’s most unique valve innovations is their spiral-shaped Powerball actuator, patented for its ability to provide a powerful torque output in an extraordinarily compact sphere-shaped package.

This versatile actuator adapts to valves from Belimo or other manufacturers, enabling seamless retrofits. Another standout Belimo technology is PICV – Pressure Independent Control Valves – designed to provide flow control unaffected by system pressure changes, critical for balancing HVAC systems.

Belimo excels at developing valve products that integrate easily into building automation environments. Open communication standards such as BACnet, Modbus, and MP-Bus allow their smart valve actuators to optimize system efficiency and visibility when connected to a building management system.

With a focus on durable products and ease of installation, Belimo’s high-performance control valve technologies continue to set new benchmarks for quality and reliability. [1]
