Steam Systems

Ensure safe and reliable system performance while reducing steam usage, leaks, and energy costs.

Steam, either generated by a boiler or provided by a energy distribution system, must be conveyed through pipework to the point where heat energy is required.

At high pressures, steam occupies a lower volume than at atmospheric pressure. The higher the pressure, the smaller the bore of pipework required for distribution of a given mass of steam. When steam condenses, its volume is dramatically reduced, which results in a pressure reduction that enables the flow of steam through the pipes.

Leaking steam valves increase personnel safety risks, energy usage, and your carbon footprint.

In most any steam system, you can find steam leaking through the stem packing of gate and globe isolation valves, wasting valuable heat energy and creating personnel safety risks.

Emerson's Vanessa™ was the industry's first triple offset valve (TOV). Its unique, non-rubbing design was created to provide bidirectional, zero leakage performance for positive isolation using a technology not previously available with other valves.

Vanessa TOV benefits versus gate and globe valves:

Unique non-rubbing, zero leakage triple offset design provides longer service life
Quarter turn operation eliminates any negative effects on packing, such as extrusion and stem abrasion that cause steam leaks and losses
Ease of manual operation and simpler to automate
A more compact gate/globe/ball valve replacement design that meets ANSI B16.10 face-to-face dimensions
Suitable for dead-end service

Our digital zone valve control solutions improve heating distribution while increasing energy efficiency.

Imagine if your home only had one heating zone, and to turn the heat on in your bedroom you had to walk to the boiler and manually open a valve. Unfortunately, facility staff in many older commercial buildings and campuses with high pressure steam systems must still manually adjust zone valves to distribute heat where needed.

Applied Control designs and implements user-friendly digital steam control solutions to tackle your most challenging two-pipe steam heating applications utilizing Emerson’s industrial quality valve, actuator, instrumentation and controls technologies.

Our HVAC application experts and Lifecycle Services engineers consult with you to determine all the nuances and details that should be considered when designing your digital steam control solution. Everything from valve, instrumentation and steam trap sizing and selection, to pipe sizing, layout, control strategy and project management requirements are reviewed to ensure success.
