Heat efficiency lose: due to the drop of throttle steam temperature caused by spray valve leakage, heat efficiency will be affected and extra heat will be needed for the boiler to keep the throttle steam temperature at the set point.
Temperature control: poor control of the steam temperature may also affect the high pressure steam pipe and turbine.
When the pressure is higher than 12.4Mpa(1800psi), each temperature change of 19-22C(30-40F) would lead to 1% heat efficiency change.
Higher maintenance cost: frequent replacement and maintenance will be needed due to the plug erosion damage.

Convista, dedicated to flow control, is a technical oriented suppliers of valves and actuators, providing quality products, services and engineer solutions, for the most challenging applications across oil and gas, refinery, power generation, petro-chemical, LNG, water system, mining, metallurgy and construction industries.
With sufficient expertise, we deliver a thorough portfolio of flow management solutions that bring vital infrastructure to different projects worldwide. We orientate towards customer demand, and help to keep smooth and safe operations, minimize downtime and enhance lifecycle performance.
Supported by Highly-trained, Experienced and Motivated Specialists
We have highly-trained, experienced and motivated specialists who understand the customer process, enabling us to offer a flexible solution suited to customer needs with quality product, optimum performance and highly responsive service.
Meeting ISO 9001, API 6D, API 6A and Other Standards
Our factories not only have to hold all major approvals, including ISO 9001, API 6D, API 6A, CE/PED, HSE and API 607/API 6Fa Fire Safe certificate, but also must have the completed control procedure from the raw materials to finished products.
We have extensive expertise in valve design, together with integrated CAD/CAM (SolidWorks) systems to fully exploit the opportunities for innovative and competitive engineering solutions whilst ensuring compliance with all relevant standards. We are not only providing technical advisory for flow control solution at the first stage, but also do a professional documentary work for whole project.
Supported by Field Engineering Service Team
And for after-service, our field engineering service team can provide timely response to customer’s needs worldwide, witness and technical support in commissioning and start up stage, maintenance shut down supervision, troubleshooting and repair service, equipment selection, maintenance, and operation training.
