The Cam-Tite Ball Valve GV Series, from ITT Engineered Valves, is a valve solution designed a direct dimensional and upgraded replacement for severe service applications. The GV Series utilizes sealing technology to isolate and contain highly hazardous liquids and gases to protect the safety of operators and prevent fugitive emissions.

The GV Series is said to offer a valve solution that is easy to operate and maintain, capable of processing ammonia, hydrofluoric acid, chlorine, ethylene oxide, phosgene, radiated media, oxygen, steam and and a number of other applications. It is available in all the same pressure classes and valve materials as the brand’s current Cam-Tite portfolio. In addition to providing valve solutions, the product line offers global customers the following benefits:

• 10 times longer stem seal life. While most globe valve designs feature stem seals that are reliable for up to 10,000 cycles, ITT Engineered Valves says the GV Series maintained zero detectable leakages for up to 100,000 cycles in tests for fugitive emissions.

• Three times higher flow design. The GV Series flow design is said to offer three times higher flow capacity than the average globe valve, intending to provide process throughput improvement and reduction of common bottlenecks.

• Ease of operation. Current globe valve designs utilize a multi-turn hand wheel design that can be difficult to operate and requires regular maintenance to function properly. The GV offers a simple turn operation, aiming to make effective shut-off easier and more convenient.

• Standard automation. Unlike older, multi-turn valve models that required custom pneumatic actuators, the GV is automated with a standard actuation package. This enables customers to standardize an actuation platform and effortlessly accommodate different valve auxiliary accessories.

• Zero seat leakage. Despite the allowable leakage range allotted for API 598 valve leakage tests, the company says the GV Series provided true zero leakage in all of its liquid and gas tests.

• In-line maintenance. The top entry design of the GV Series makes onsite or in-line repair quick and simple. Standard welded bellows stem seal globe valves often require repairs at an authorized service center.

“When managing harsh applications, a proven, effective valve is critical to avoid costly and dangerous disruptions,” says Nang Chau, ITT Engineered Valves global product manager. “That’s why our GV Series utilizes advanced technology that not only complies with industry performance standards, but exceeds them. Enhancements made to the GV Series seal and flow designs outperform average globe valves in preventing emissions of harsh chemicals, highlighting our continued commitment to protecting the safety of machine operators and the environment.”

The product line follows an important milestone achieved by Engineered Valves’ Cam-Tite Top Entry Ball Valves line. The line earned a Safety Integrity Level (SIL) 3 Capable certification to IEC 61508 in compliance with International Electrotechnical Commission standards. It also passed several advanced testing standards for fire safety, harsh conditions and fugitive emission prevention, including API 607, API 598, ANSI/FCI 70-2, API 622, EPA Method 21, ISO 15848, ASME B31.3 Category M, NACE Standard MR01-75 and Chlorine Institute Pamphlet 6.
