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 efciency—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...

Designed for maximum reliability Becker T-Ball Anti-Surge Valves can be custom designed for your application and manufactured with superior quality materials to deliver reliability and protection for your system. ANTI-SURGE CONTROLLER T-Ball® Anti-Surge Valve Check Valve Centrigal or Axial Compressor Gas Turbine Typical Anti-Surge System Becker T-Ball Anti-Surge Valves can operate in the critical conditions compressor stations demand, from high pressure differentials, extreme temperatures to corrosive media.

Each component is engineered to provide exceptional performance Controlled Deceleration A pneumatic cushion engaged in the last 10% of travel prevents impulse loading from a surge’s quick, high force stroking speeds—reducing frictional effects that can occur within the unit. Heavy Duty Pneumatic Cylinder The Becker RPSR actuator assembly utilizes a high pressure durable steel pneumatic cylinder that offers very low break loss pressure. Superb Fatigue Resistance Heavy duty spring material manufactured from heat treated 6150H steel alloy provides a very long life. Improved Safety An...

Improve compressor operating efciency Combining the superior control of a Becker T-Ball and rotary actuator with the speed and accuracy of a Becker HPP-SB or SVI® II AP positioner, provides the complete anti-surge valve solution. This enables your compressor to operate as close as possible to the surge line—maximizing efficiency without jeopardizing performance. Pneumatic positioner Additional equipment not required to power Powered by pipeline gas instrumentation Provides optimum speed of response and High capacity (Cv) control required for anti-surge valves Rugged construction Vibration...

Maximized control and capacity Flow Prole for 8” (200 mm) QTCV-T2 Surge Region Recycle Region Excess Capacity Degrees Travel (Open) Many cage style valves achieve fast operating speeds by sacrificing the dynamic performance of the valve at low flow conditions. The equal percentage characteristic of a Becker T-Ball offers uncompromising control at both start-up (low flow/high) and surge. Additionally, because of the T-Ball’s unique flow characteristic it is able to perform the functions of both a recycle valve and an anti-surge valve, with excess capacity for the most extreme conditions. One...

Additional protection Multiple valves may be used in the surge control system to meet the unique demands of both the process control and emergency shutdown operations. GE offers additional Becker valves such as the Hot Gas Bypass and Station Recycle Valves that can be used to meet the response time or flow rate requirements. ASV Hot Gas Bypass (HGBP) Valves are employed to provide additional protection against surge. During normal operation, the valve remains closed until a safety critical trip is detected requiring a compressor emergency shutdown. The HGBP valve then springs to open,...

Meeting size requirements Although all control valves are sized according to process conditions, anti-surge applications require particular attention. Anti-surge valves typically must meet two sizing requirements: 1. Enough capacity to recycle the compressor, yet not be oversized which can choke the flow to the compressor 2. Capacity to depressurize the discharge in less than one second Through taking your compressor’s performance into account from start-up to surge, GE Oil & Gas has mastered the art and science of sizing anti-surge valves. The T-Ball’s combination of high capacity and high...

Assuring your needs are met We understand how critical it is to keep your system up and running. When it comes to protecting your compressor, GE Oil & Gas makes no compromises. In order to assure exceptional performance in the field, each Becker T-Ball anti-surge valve undergoes several validation tests before leaving our factory. Upon test completion you will be provided with a customized performance analysis to confirm our anti-surge valve has met all performance requirements. The table below provides a sample of our recommended dynamic parameters. Test Parameter Full opening by automatic...

Field Proven in some of the most inhospitable environments Location: Natural Gas Production Field Becker T-Ball Anti-Surge Valves were selected to protect the compressors of one of the world’s largest natural gas production fields. Located in the remote subarctic zone, temperatures are below freezing over 250 days of the year – it is not uncommon for temperatures to drop below -65°F (-55°C). For an operation of this scale, the customer relied on GE to provide the technology that is critical to maintaining continuous and stable control. GE engineers traveled to the site to conduct a field...
