Becker* T-Ball* Anti-Surge Valve

High performance compressors require high
performance surge protection

Background Image: Becker T-Ball* anti-surge valve installed
in a Russian natural gas processing plant providing reliable
protection for nearly a decade.

Becker T-Ball* Anti-Surge valves from GE Oil & Gas
provide precise anti-surge protection and control
for critical compressor applications across the oil
and gas industry. Our patented rotary-control,
non-clogging T-Ball design provides fast, low
impact automation that helps eliminate potentially
damaging pressure imbalances while reducing
maintenance and increasing effi ciency—all
without compromising performance. And the
T-Ball’s unique combination of high capacity and
high turndown offers superior control and
protection throughout the compressor’s speed
range. The Becker T-Ball anti-surge valve is a
complete anti-surge control solution that delivers
high performance and reliable protection even in
the most demanding operating environments.

Combined, these performance features
provide the following added benefi ts:

■

Exceptional continuous control

■

Fast response and protection of critical equipment

■

Improved system operating efficiency

■

Increased profitability with minimal energy loss

■

Reduced maintenance and tuning

The patented rotary control T-Ball features a
non-clogging quarter-turn design that provides
quick and low impact automation. Its high capacity
and rangeability combined with multi-stage noise
attenuating trims makes it ideal for demanding
anti-surge applications.
