An ultrasonic survey in 2014 revealed steam losses costing £23,000 annually. Boiler tests also faced pressure loss challenges. In 2016, V1 ball valves were installed, solving these issues.
A power generation facility was using various valve types for isolation of high-pressure and/or high-temperature steam and water in their heat recovery steam generator and steam turbine systems, but persistent issues with these Y-Type globe, angle, butterfly, and gate valves were causing major efficiency losses that plagued the plant.
A world-renowned OEM was experiencing difficulties brought on by 70 leaking globe valves in high-temperature, high-temperature severe service applications. ValvTechnologies addressed and resolved a number of the OEM’s concerns with its innovative technology, optimizing the plant’s performance, saving the customer time and money.
ValvTechnologies met with an OEM’s HRSG design engineering team to inquire about issues they were experiencing with their plant’s globe valves. Learn how ValvTechnologies became their reliable partner and trusted advisor, and how they began the process of changing from traditional globe valves to modern advanced technology ball valve designs.
The plant had two main steam isolation PSG valves installed in this application. They were experiencing severe leakage when valves were required to isolate. From initial plant start-up, the frequency of valve maintenance of up to twice per year per valve. The cost of $40,000 per repair, was a particular concern for the plant.
