CCI / BTG VALVES

In 2001 BTG Specialty Valves was acquired by CCI and changed its name to

CCI Sweden. The products are branded “BTG Valves.”

CCI is the world’s leading manufacturer of severe-service control valves and

hydraulic and pneumatic actuators. CCI provides engineering solutions

for control valves in fossil and nuclear power plants, the oil and gas

industries, and pulp and paper facilities. With headquarters in Rancho

Santa Margarita, California, and sales offices worldwide, CCI also operates

major design and manufacturing facilities in Säffle, Sweden; Winterthur,

Switzerland; Osaka, Japan; and Kyunggi-Do, the Republic of Korea.

Innovations have played a major part in the BTG Valves success story. For

more than 80 years a steady flow of new products has been helping to meet

customers’ specific needs to improve functionality and reliability while at

the same time helping them to optimize the industrial process in general.

In 1929, BTG Valves concluded that combining pressure and temperature

reduction in a single valve body was the key to optimal controllability and

turndown. In the unique BTG valve, combined valve functions are mastered

and long lifetime is assured.

Apart from approved function, combining pressure and temperature

reduction in a single valve body means less rigorous requirements for piping

downstream from the steam conditioning valves, i.e., shorter and straighter

pipe runs and shorter distances to the temperature sensor.

In situations where cooling without pressure reduction is required, a

desuperheater is used. Desuperheaters from BTG Valves are designed to

optimize the atomization of the cooling water for fast evaporation and

maximum rangeability.

Applications

BTG Valves are primarily designed for pressure and temperature control of

steam in severe applications such as:

n Turbine Bypass Valves

n Process Steam Conditioning Valves

n Pressure Relief Valves

In addition to steam valves and desuperheaters BTG Valves are used in

applications such as:

n Boilerfeed Water Control

n Pump Recirculation

n Spraywater Control

n Boiler Drum Blow Down

n Feedwater Preheater Bypass
