Compact Ball Valves

Long Device Life

With the Whisperjet, steam impinges itself to reduce pressure as it flows through a series of multi-pressure reduction stages. Steam does not rely solely on a tortuous path like most pressure letdown devices; thus, there is virtually no part erosion, which you would commonly see in orifice plates or other pressure letdown devices.

Longer System Life

When Whisperjets are used in conjunction with a valve or other system components, the seat life of the valve is substantially increased. When used before a condensor or flash tank, baffel and tank wear are greatly reduced.

Reliable

Whisperjets have been installed in power plant applications around the world for over 25 years. They are proven to be rugged and reliable in high-pressure environments.

Reduced Noise

Each section has 4-6 orifices around its perimeter. The orifices discharge inwardly, which reduces the steam pressure without causing component wear. Pressure is reduced in stages, which prevents a critical pressure drop. Each stage is progressively larger, allowing the steam to expand. The orifices are sized to keep the flow of steam below critical velocity. This gives the advantage of reduced noise.

Economical

Due to their simple, practical design and operation, Whisperjets are low-cost solutions to steam erosion problems.

Flexible

The number of Whisperjet stages may be varied for almost any flow requirement. Our engineering department will work with you to custom-specify Whisperjet to meet your needs.
