Steamcontrol valve

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.

Series 009 Reduced Pressure Zone Assemblies are designed to protect potable water supplies in accordance with national plumbing codes and water authority requirements. This series is designed to protect drinking water supplies from dangerous cross-connections in accordance with national plumbing codes and water authority requirements for non-potable service applications such as irrigation, fire line, or industrial processing. This series features two in-line, independent check valves, captured springs and replaceable check seats with an intermediate relief valve. Its compact modular design facilitates easy maintenance and assembly access. Sizes 1⁄4 – 1 inch shutoffs have tee handles. Assembly meets AS/NZS 2845.1 Standards.

Steam RegulatorValve

Controlling the temperature of saturated steam does not have to be complicated. With the acquisition of the Burling Valve 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.

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.

SteampressureRegulator

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.

Proportion-Air & Burling Valve steam regulators are available in a variety of mechanical and electronic control types and configurations

All of the internal components can be easily replaced without removing the valve from the pipeline. This allows for much greater online productivity.

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.

For decades, controlling the temperature of saturated steam has been complicated, expensive and extremely inefficient. Imagine if your saturated steam control valves could:

However, the electronic controller does not know the pressure in the main line and cannot adjust to leaks, backpressure and mechanical deficiencies.
