Saturated Steam Control Valves
Controlling the temperature of saturated steam does not have to be complicated. With the acquisition of the Burling Valve steam regulator brand, Proportion-Air secured an excellent opportunity to help improve how the manufacturing industry controls the temperature of saturated steam. Control valves will always have a place in manufacturing, but steam regulators are the future of saturated steam control valves.
The Proportion-Air saturated steam control valves and regulators control pressure. Since the pressure of saturated steam is directly related to its temperature…we simply control temperature.

Less Expensive
Initial & lifetime cost is (generally) less with steam regulators compared to traditional control valves.
On-Board PID
No PID tuning required (with electronic control option). Command to pressure & temp. is achieved.
Less Maintenance
The easy in-line maintenance of the Burling Valve steam regulator requires much less downtime.
Better Control
Steam regulators are much quicker to temperature and much more stable during your process.
Advantages of Steam Regulators over Traditional Control Valves
Time for a Change
For decades, controlling the temperature of saturated steam has been complicated, expensive and extremely inefficient. Imagine if your saturated steam control valves could:
- Achieve temperature 75% faster
- Be more accurate and stable during your process
- Easily be repaired without removing the valve from the line – in just a couple hours
- Be installed and controlled without requiring complicated PID tuning
How do Proportion-Air & Burling Valve improve your steam control process?
- It’s simple: We work with physics instead of working around it. We control the pressure of saturated steam because the pressure of saturated steam is directly related (predictable & repeatable) to the temperature of saturated steam.
Traditional Method
Temperature achieved in 45 minutes
Preferred Method
Temperature achieved in 10 minutes
Proportion-Air & Burling Valve steam regulators are available in a variety of mechanical and electronic control types and configurations
Pressures
up to 400 PSI (28 Bar)
Body Sizes
1/2″ to 4″ with the option of 6″ & 8″ Flanges
Temperatures
up to 450°F (232°C)
Mechanical Control Types & Configurations
BS-1 Series
Direct Operated (Spring)
Internally or Externally Sensed
Accuracy: ± 7 PSI
BD-3 Series
Dome-Loaded with Manual Air Pilot
Internally or Externally Sensed
Accuracy: ± 1-2 PSI
BD-7 Series
Dome-Loaded with Steam Pilot
Accuracy: ± 0.1 to 0.2 PSI
Electrical Control Types & Configurations
BD-4 Series
In single-loop configuration, the electronic pilot controls pressure to the dome of the BD steam regulator. As the diaphragm forces equal out, the pressure in the main line is controlled.
However, the electronic controller does not know the pressure in the main line and cannot adjust to leaks, backpressure and mechanical deficiencies.
Accuracy: ± 2-4%
BD-4 Series
With dual-loop control, the electronic pilot controls pressure to the dome of the BD steam regulator. As the diaphragm forces equal out, the pressure in the main line is controlled.
But, instead of sensing pressure in the dome, a 2nd-loop is added that senses pressure in the main line and allows the electronic regulator to compensate for leaks, backpressure and any mechanical deficiencies.
Accuracy: ± 0.5%
Easy In-Line Maintenance
All of the internal components can be easily replaced without removing the valve from the pipeline. This allows for much greater online productivity.
