Our company was founded in 1990 as a technical consultancy specialized in control valves and, more precisely, severe duty control valves for critical services.

Our partners, having served world leaders in this field, MN, FC, CV, CCI and others, enjoy many years of experience.

The philosophy of our company has always been to offer valve manufacturers and end users the best solutions to problems associated with critical conditions.

Critical conditions are due most times, but not only, to high pressure drop across the valve, with the results of cavitation in liquids, or sonic conditions in gases.

Our valve designs go to the origin of the problem and suppress both, cavitating and sonic conditions (“source treatment”).

Other areas of our activity related to control valves include increase of valve rangeability, capacity to travel characteristic, pilot operated plug or self actuated valves.

MULTISTAGE DESIGNS

Multistage designs are the preferred solution to deal with critical conditions.

Our designs of valve internal components for critical service, are based on the multistage-multichannel principles:

      – total flow is dispersed into small flow channels,

      – total pressure drop is divided into several smaller -non critical- pressure steps.

Calculation of the number of steps and the Cv values of every stage, allow to suppress cavitation or sonic conditions at any point inside the valve.

THE MARKET

The market of heavy duty control valves, for critical services is an important part of the total control valve market.

Critical conditions are encountered in fossil and nuclear power plants, pipelines, refineries, HCP and other process industries.

Some examples of critical applications are compressor surge control, pump recirculation, gas to flare, or boiler feed water and start-up, leak-off, turbine bypass, deaerator level control or heaters drain in power.

Our customers are control valve manufacturers serving the above mentioned power, gas, chemical, petrochemical, industries and pipelines.

We offer the technology and assistance required to help the valve manufacturers to enter/increase their share in this -most exacting and also more profitable- heavy duty valves market. Complete “valve packages” are made possible.

In many cases manufacturer´s standard valves have been upgraded just by replacing internal parts of the valve.
