The correct valves, piping and fittings are critical to the successful operation of power generation equipment. The equipment includes products with a variety of designs that can establish effective connection and sealing methods, and have better connection integrity, thereby ensuring safe operation in thermal, nuclear and renewable energy power plants. The manufacturer points out that when promoting its products, installation costs are lower, safety and efficiency are improved, and planned and unplanned maintenance downtime are reduced. Here are some leading manufacturers and service companies of power plant valves, pipes and fittings. Boldrocchi completed the successful test of its new 7m by 7m diverter valve for gas turbines earlier this year. The diverter valve is a three-way valve that can discharge the gas turbine exhaust gas to the atmosphere through the bypass chimney, or into the heat recovery steam generator. The damper has an extremely high capacity and exceeds the standard in terms of geometric sealing, sealing pressure and closing time, while reducing maintenance and simplifying transportation and assembly. This new diverter also allows a rapid transition from a single cycle system to a combined cycle system. It is designed to withstand temperatures up to 700C (1,300F), vibration and gas turbulence, and improve component wear. The diverter is equipped with an air sealing system, which can make the sealing degree of the exhaust gas equal to 100% (complete sealing). The air seal pressure is greater than +500 mm of water column (mm wc), and the original equipment manufacturer usually requires +50 mm wc. The shunt is equipped with a hydraulic actuator. According to customer requirements, its normal operation time is less than 60 seconds, and the emergency shutdown time is less than 20 seconds. However, the shunt is designed and manufactured to shorten the driving time. Boldrocchi designed the splitter to make it easy to transport and assemble. The splitter can be pre-assembled into several pieces, or it can be fully assembled and delivered (one part). Boldrocchi designed the splitter to be easily installed under the single-cycle exhaust chimney instead of the existing elbow. Boldrocchi, Biassono, Italy Spirax Sarco Engineering Co., Ltd. provides products and services for thermal energy solutions. Its Spira-trol modular control valve has been put into use at the factory, allowing quick "plug and play" installation. Spira-trol's modular design has a quick-change "clamp-in-place" valve seat, which means its task can be changed to adapt to changing plant conditions without having to replace the entire valve. The self-aligning in-situ clamping valve seat also simplifies maintenance, so no special tools are required, and there is no need to remove the valve from the pipeline. This can save a lot of cost compared to traditional designs that usually have a fixed screw-in valve seat. The screw-in valve seat is often stuck in place, requiring the valve to be disassembled, resulting in long plant downtime. Provide 1/2 inch to 4 inch electric and pneumatic Spira-trol valve, up to ANSI 150 flange version. With a complete Spira-trol product series (expandable to 8 inches) and ANSI 600 pressure range, Spirax Sarco can provide control solutions from heating, ventilation and air conditioning to process and power to demanding service applications. Spirax Sarco, Cheltenham, UK Clark Valve Company announced that its proprietary gate valve design has received API 641 certification, which is the first control valve to receive this low emission performance certification. The API 641 standard applies to all valve stem sealing materials, and the strict maximum allowable leakage is 100 parts per million by volume (ppmv). This API test standard requires the valve to take 610 cycles under extreme temperature fluctuations to evaluate the emission performance during the accelerated life cycle. Fugitive emissions from traditional valve designs in industrial facilities are the main cause of air pollution, and the unique design of gate valves provides excellent sealing at the valve stem, thereby reducing these emissions. The patented shutter valve was independently tested by Yarmouth Research and Technology. The valve proved that the valve passed a leak test of less than 20 ppmv, well below the 100 ppmv limit. The unique design of the shutter valve is already the best performance control valve in the world, and now it is also the most environmentally friendly control valve ever.
